When Israeli Warplanes Rain Death on Gaza, the Co-Pilot Is Uncle Sam

Originally published on TomDispatch:

In recent weeks, political soothsayers have speculated about a wide variety of odious new policies the incoming Trump administration and its allies in Congress may or may not pursue. No one can predict with certainty which of those measures they will inflict on us and which they’ll forget about.  But we can make one prediction with utter confidence. The White House and large bipartisan majorities in Congress will continue their lavish support for Israel’s war on Gaza, however catastrophic the results.

Washington has supplied a large share of the armaments that have allowed the Israeli Defense Forces (IDF) to rain death and destruction on Gaza (not to speak of Lebanon) over the past year and a quarter. Before October 7, 2023, when Hamas and other groups attacked southern Israel, that country was receiving $3.8 billion worth of American military aid annually. Since then, the floodgates have opened and $18 billion worth of arms have flowed out. The ghastly results have shocked people and governments across the globe.

In early 2024, the United Nations General Assembly and International Court of Justice condemned the war being waged on the people of Gaza and, in November, the International Criminal Court issued arrest warrants for Prime Minister Benjamin Netanyahu and Defense Minister Yoav Gallant for war crimes and crimes against humanity. Amnesty International, Human Rights Watch, the European Center for Constitutional and Human Rights, and Médecins Sans Frontières all followed with determinations that Israel was indeed committing genocide.

This country’s laws and regulations prohibit aid to military forces deliberately killing or wounding civilians or committing other grave human rights abuses. No matter, the U.S.-to-Israel weapons pipeline has kept right on flowing, completely unchecked. A cornucopia of military funds and hardware for Israel in the early months of the war came from just two nations: 69% from the United States and 30% from Germany.

Were it just about any other country than Israel committing such a genocide, Washington would have cut off arms shipments months ago. But U.S. leaders have long carved out gaping exceptions for Israel. Those policies have contributed mightily to the lethality of the onslaught, which has so far killed at least 52,000 Palestinians, 46,000 of whom are believed to have been civilians. And of those civilian dead, five of every six are also believed to have been women or children. Israeli air strikes and other kinds of bombardment have also destroyed or severely damaged almost half a million housing units, more than 500 schools, just about every hospital in Gaza, and large parts of that region’s food and water systems — all with dire consequences for health and life.

Bombs Leave Their Calling Cards

From October 2023 through October 2024, reports Brett Murphy at ProPublica, 50,000 tons (yes, tons!) of U.S. war matériel were shipped to Israel. A partial list of the munitions included in those shipments has been compiled by the Costs of War Project. The list (which, the project stresses, is far from complete) includes 2,600 250-pound bombs, 8,700 500-pound bombs, and a trove of 16,000 behemoths, each weighing in at 2,000 pounds. In January 2024, Washington also added to Israel’s inventory of U.S.-made F-15 and F-35 fighter jets. Naturally, we taxpayers footed the bill.

As Abigail Hauslohner and Michael Birnbaum of the Washington Post noted in late October, “The pace and volume of weaponry have meant that U.S. munitions make up a substantial portion of Israel’s arsenal, with an American-made fleet of warplanes to deliver the heaviest bombs to their targets.” When confronted with solid evidence that Israel has been using U.S. military aid to commit genocide, National Security Adviser Jake Sullivan told reporters, “We do not have enough information to reach definitive conclusions about particular incidents or to make legal determinations.”

Really? How much information would be enough then? Isn’t it sufficient to see Israeli forces repeatedly target clinics, homes, hospitals, mosques, and schools with massive, precision-guided bombs? Isn’t it enough when the IDF targets the very “safe zones” in which they have commanded civilians to take shelter, or when they repeatedly bomb and strafe places where people have gathered around aid trucks to try to obtain some small portion of the trickle of food that the Israeli government led by Netanyahu has decided to allow into Gaza?

If the U.S. State Department’s analysts really were having trouble making “definitive conclusions about particular incidents,” then Stephan Semler was ready to lend a hand with a report at the Quincy Institute for Responsible Statecraft entitled “20 Times Israel Used U.S. Arms in Likely War Crimes.” Worse yet, his list, he points out, represents only “a small fraction of potential war crimes committed with U.S.-provided weapons,” and all 20 of the attacks he focuses on occurred at locations where no armed resistance forces seemed to be present. Here are a few incidents from the list:

When warplanes bombed a busy market in northern Gaza’s Jabalya refugee camp, killing 69 people in October 2023, U.N. investigators determined that U.S.-made 2,000-pound GBU-31 air-dropped munitions had been used. A couple of weeks later, the U.N. found that “several” GBU-31s were responsible for flattening a built-up area of more than 60,000 square feet within Gaza City, killing 91 people, 39 of them children. A weapon dropped on a residential building last January, killing 18 (including 10 children), left behind a fragment identifying it as a 250-pound Boeing GBU-39. An airstrike on a tent camp for displaced people in Rafah in May, killing 46 people, left behind a GBU-39 tailfin made in Colorado. The next month, a bomb-navigating device manufactured by Honeywell was found in the rubble of a U.N.-run school where 40 people, including 23 women and children, had been killed. In July, more than 90 people were slaughtered in a bombing of the Al-Mawasi refugee camp, an Israeli army-designated “safe zone” near the southwest corner of Gaza. A tailfin found on the scene came from a U.S.-built JDAM guidance system that’s commonly used on 1,000- or 2,000-pound bombs. Also in July, fragments of the motor and guidance system of a Lockheed-Martin Hellfire missile fired from a U.S.-made Apache helicopter were found in the remains of a U.N.-run school where refugees were sheltering. Twenty-two had been killed in the attack.

“Everyone Knew the Rules Were Different for Israel”

In December, a group of Palestinians and Palestinian-Americans filed a lawsuit in federal court accusing the State Department of violating a 1997 act of Congress that prohibits arms transfers to any government that commits gross human rights violations.

As the Guardian reported, a large number of countries “have privately been sanctioned and faced consequences for committing human rights violations” under the act, which is known as the “Leahy law” after its original sponsor, former Senator Patrick Leahy of Vermont. But since 2020, a special committee, the Israel Leahy Vetting Forum (ILVF), has decided whether payments or shipments destined for Israel should be permitted. According to the Guardian, Israel has “benefited from extraordinary policies inside the ILVF,” under which arms transfers get a green light no matter how egregiously Israeli occupation forces may have violated human rights. In the words of a former official, “Nobody said it, but everyone knew the rules were different for Israel.”

According to the Post‘s Abigail Hauslohner and Michael Birnbaum, the process of determining whether Israel is using U.S.-supplied weapons to commit war crimes “has become functionally irrelevant, with more senior leaders at the State Department broadly dismissive of non-Israeli sources and unwilling to sign off on action plans” for disallowing aid. A midlevel department official, once stationed in Jerusalem, told Post reporters that senior officials “often dismissed the credibility of Palestinian sources, eyewitness accounts, nongovernmental organizations… and even the United Nations.” So, the arms have continued flowing, with no letup in sight.

In January 2024, Jack Lew, the Biden administration’s ambassador to Israel, sent a cable to top State Department officials urging that they approve the IDF’s request for thousands of GBU-39 bombs. Lew noted that those weapons were more precise and had a smaller blast radius than the 2,000-pound “dumb bombs” Israel had been dropping in the war’s early months. Furthermore, he claimed, their air force had a “decades-long proven track record” of avoiding civilian deaths when using the GBU-39.

That was, unfortunately, pure eyewash. At the time of the cable, Amnesty International had already shown that the Israeli Defense Forces were killing civilians with GBU-39s. The State Department nevertheless accepted Lew’s claims and approved the sale, paving the way for even more missiles and bombs to rain down on Palestinians. In reporting on the Lew cable, ProPublica‘s Brett Murphy wrote, “While the U.S. hoped that the smaller bombs would prevent unnecessary deaths, experts in the laws of war say the size of the bomb doesn’t matter if it kills more civilians than the military target justifies.” That principle implies that when there is no military target, an attack causing even one civilian casualty should be charged as a war crime.

During 2024, with its unrelenting bombardment of Gaza and then Lebanon, too, Israel chewed rapidly through its munition stocks. The Biden administration came to the rescue in late November by approving $680 million in additional munitions deliveries to Israel — and that was just the appetizer. This month, ignoring Israel’s 15 months of brutal attacks on Gaza’s population, the administration notified Congress of plans to provide $8 billion worth of additional arms, including Hellfire missiles, long-range 155-millimeter artillery shells, 500-pound bombs, and much more.

Big Death Tolls Come in Small Packages

International bodies have accused Israel of using not only bombardment but also direct starvation as a weapon, which would qualify as yet another kind of war crime. In early 2024, responding to pressure from advocacy groups, Joe Biden signed a national security memo designated NSM-20. It required the State Department to halt the provision of armaments to any country arbitrarily restricting the delivery of food, medical supplies, or other humanitarian aid to the civilian population of an area where that country is using those armaments. But the memo has made virtually no difference.

In April, the two top federal authorities on humanitarian aid — the U.S. Agency for International Development (USAID) and the State Department’s refugee bureau — submitted reports showing that Israel had indeed deliberately blocked food and medical shipments into Gaza. Under NSM-20, such actions should have triggered a cutoff of arms shipments to the offending country. But when the reports touched off a surge of outrage among the department’s rank and file and demands for an arms embargo, Secretary of State Antony Blinken and other top brass steamrolled all objections and approved continued shipments, according to Brett Murphy of ProPublica.

Another dimension of Israel’s war-by-starvation has been illustrated and quantified in a spatial analysis published by the British-based group Forensic Architecture. See, for example, the maps and text on pages 252–258 of their report, which reveal in stark detail the extent to which Israeli forces have ravaged agricultural lands in Gaza. Alongside bombing, shelling, and tank traffic, bulldozers have played an outsized role in the near-obliteration of that area’s food production capacity. The model D-9 bulldozers that are used to demolish Gaza’s buildings and lay waste to her farmland are manufactured by Caterpillar, whose global headquarters is in Texas.

In the early months of the war, Biden administration officials also took advantage of federal law, which doesn’t require that military aid shipments whose dollar value falls below certain limits be reported. They simply ordered that the huge quantities of arms then destined for Israel be split up into ever smaller cargoes. And so it came to pass that, during the first five months of the war, the Biden administration delivered more than 100 loads of arms. In other words, on average during that period, an American vessel laden with “precision-guided munitions, small diameter bombs, bunker busters, small arms and other lethal aid” was being unloaded at an Israeli dock once every 36 hours.

Israeli pilots have used U.S.-built fighter jets for the lion’s share of their airstrikes on Gaza and, by last summer, even more aircraft were needed to sustain such levels of bombing. Of course, jets are too big and expensive to be provided covertly, so, in August, Secretary of State Blinken publicly approved the transfer of nearly $20 billion worth of F-15 jets and other equipment to the IDF. The aircraft account for most of that sum, but the deal also includes hundreds of millions of dollars worth of ground vehicles and tank and mortar ammunition.

In September, Bernie Sanders, who served in Congress alongside Patrick Leahy from 2007 until the latter’s retirement in 2023, further enhanced the good reputation of Vermont senators by introducing three resolutions that would have blocked the State Department’s $20 billion Israel aid package. But when the measures came up for a vote in November, all Republicans, along with two-thirds of Sanders’s fellow Democrats, joined forces to vote them down. So, as always, Israel will continue to get its jets, tanks, and ammo.

With scant political opposition, the new Republican-controlled Congress and Trump White House will undoubtedly only double down on material support for Israel’s war crimes. And they are already threatening people who demonstrate publicly in support of an arms embargo with investigation, prosecution, deportation, or other kinds of attacks. Citing those and other threats, Ben Samuels of Haaretz anticipates that Trump’s promise “to crack down on pro-Palestinian sentiment in America will be a defining factor of his administration’s early days” and that “the fight against the pro-Palestinian movement might be one of the only things that has a clear path across the government” — that is, the suppression could be bipartisan. For the people of Gaza and their American supporters, 2025 could turn out to be even more horrifying than the ghastly year just passed.

Gaza: A Perception Gap


“What the eye does not see, the heart can not feel” is a proverb well known to malefactors. Today, most Americans have not seen what is truly taking place in Gaza. This is by design – Israeli design.

More than a year ago a report in Foreign Policy stated that on Israeli television “you are unlikely to see the suffering and death or even the faces of Palestinian civilians”, and that the “coverage could be leading to a perception gap about the war in Gaza.”

But not only does Israel not want its citizens to see what is happening in Gaza, Israel does not want the world to see. From the beginning of the war Israel has excluded all foreign journalists from Gaza, an unprecedented action according to the head of the Committee to Protect Journalists (CPJ).

In April 2024, Israel authorized the Prime Minister to shut down any foreign channel considered a “threat to national security”, and in May Al Jazeera was shut down and its equipment seized. Reporters Without Borders criticized Israel for “using every possible method to try to silence Al Jazeera for its coverage of the reality of the fate of Palestinians”.

In July 2024 the Foreign Press Association blasted Israel for imposing an “information blackout” on Gaza which “raises questions about what Israel doesn’t want international journalists to see”.

Of course, there were Palestinian journalists in Gaza. Israel has tried to silence them as well – by killing them. More journalists have been killed in Gaza in a shorter period of time than in any other conflict in modern history. At least 160 media workers have been killed according to the CPJ, and “at least 11 journalists and two media workers were directly targeted by Israeli forces in killings which CPJ classifies as murders.” The targeting of civilian journalists constitutes a war crime under international law.

An analysis of the coverage of the war in Gaza by The New York Times, Washington Post, and Los Angeles Times during the first six weeks of the conflict (Oct 7 to Nov 24) done by the news organization, The Intercept, showed a consistent bias against Palestinians. “Highly emotive terms for the killing of civilians like ‘slaughter,’ ‘massacre,’ and ‘horrific’ were reserved almost exclusively for Israelis who were killed by Palestinians”. It also found glaring disparities in the reporting of the killing of children which was extensive in the Ukraine war and far less in Gaza.

A report in The Nation in October 2024 found similar biases against Palestinians by the two cable news outlets CNN and MSNBC as well as similar disparities between reporting on the war in Ukraine versus the war in Gaza.

In December 2024 a report in The Nation found that NBC’s Meet the Press, ABC’s This Week With George Stephanopoulos, CBS’s Face the Nation, and CNN’s State of the Union with Jake Tapper and Dana Bash, with the exception of one interview, covered the war in Gaza for “12 months without speaking to a single Palestinian or Palestinian American.” In contrast, the show featured Israeli guests 20 times including Benjamin Netanyahu 5 times.

This bias is not limited to US media outlets. In November 2024 more than 100 staff accused the BBC of pro-Israel bias in reporting on the war in Gaza.

Nor is this bias of recent origin. The Washington Post in May 2021 ran the following article: “Facebook’s AI treats Palestinian activists like it treats American Black activists. It blocks them.” In June 2021 almost 200 Facebook employees signed a letter protesting the regular disappearance of Palestinian voices from the platform.

Not only does Israel seek to silence criticism in the media but also in the halls of government. In the 2024 election the pro-Israel American Israel Public Affairs Committee (AIPAC)  and its affiliated super PACs vowed to spend more than $100 million on more than 80% of the races in the Senate and House. In December 2024 Israel’s Foreign Ministry budget for 2025 proposed to increase its spending to promote Israel’s image abroad by 20 times to $150 million.

Of course, Israel has a well-rehearsed response to those who would seek to hold it accountable for its actions. It is to use the tactic called DARVO: deny, attack, and reverse victim and offender. Israel denies the allegation, attacks it as antisemitic, and alleges that in reality Israel is the only victim.

Voltaire once said, “We owe respect to the living; to the dead we owe only truth.” The responsibility of the media to both the living and the dead in Gaza is to shine a light on what others seek to hide, not to be complicit in its concealment.

Climate change is melting away glaciers around the world, but in the Andes Mountains, a wild relative of the llama is helping local ecosystems adapt to these changes by dropping big piles of dung.

This finding, published Dec 30 in Scientific Reports, revealed that the activity of this animal could accelerate the time plants usually take to establish on new land by over a century, highlighting a surprising way organisms are adapting to climate change.

“It’s interesting to see how a social behavior of these animals can transfer nutrients to a new ecosystem that is very nutrient poor,” said Cliff Bueno de Mesquita, the paper’s co-first author and a research scientist in the Cooperative Institute for Research in Environmental Sciences at CU Boulder. But the current pace of climate change still outpaces the ability of species to find new habitats, he warned. 

The changemakers here are the vicuñas. They are one of two wild South American camelids, a group of animals that includes alpaca and llama, which are domesticated species. They live in the high alpine areas of the Andes. 

Vicuñas may be less famous than their celebrated llama cousins, but they are no less remarkable, particularly because of where they choose to poop.

Much like how humans use bathrooms, these animals get rid of their solid waste using a designated spot shared by multiple members of a social group. Scientists refers to these communal dung piles as latrines.

Over the past two decades, Steven Schmidt, the paper’s senior author and professor in the Department of Ecology and Evolutionary Biology, has studied how microbial life and plants are responding to retreating glaciers in the high-altitude Peruvian Andes.

The deglaciated soils are extremely depleted of nutrients and water—a sea of rocks and gravel that can remain plant-free for over a century.

But during expeditions over the last ten years, Schmidt and his collaborators began noticing patches of plants, all of which seemed to have emerged from vicuña poop piles.

Working with animal ecologist Kelsey Reider at James Madison University, the team trekked to sites in the Peruvian Andes, up to 18,000 feet above sea level, that were previously covered by glaciers. They sampled vicuña latrine soils in these areas and found that, compared to barren soils just a few feet away, soils with vicuña poop contained significantly more moisture and key nutrients, like organic carbon, nitrogen and phosphorus.

For example, latrine soil was made of 62% organic matter. In contrast, deglaciated soil that has been exposed for 85 years at the same location but without latrines contained only 1.5% organic matter.

At high elevations, temperatures tend to fluctuate significantly throughout the day, dropping below freezing every night even during the summer. “It's really hard for things to live, but that organic matter made it so that temperatures and moisture levels didn't fluctuate nearly as much. The latrines created a different microclimate than the surrounding area,” Schmidt said.

The team also found high DNA concentrations and a wide diversity of microorganisms in latrine soil samples, suggesting that the latrines provided vital ground for microbes and plants to thrive.

The team said vicuña dung likely accelerated the timeline for plants to colonize a barren, lifeless habitat by a century. These animals deposit nutrients and plant seeds from lower elevations in their poop onto deglaciated ground, and then the seeds germinate, attracting other organisms, including animals that feed on the plants.

Camera footage showed that the patches of plants have attracted all kinds of animals, including rare species never before seen at such high elevations and large carnivores like puma. Vicuñas also eat the vegetation growing in their own latrines.

It could take hundreds of years for the deglaciated area to transition into grassland, which might help mitigate the negative impacts that many species preferring colder climates face as their habitats shrink from climate change, Reider said.

But even with the vicuña’s help, the rate of species colonizing new ground is much slower than the rate at which the glaciers are retreating.

Glacier melt across the world has accelerated over the past two decades. Between 2000 and 2019, glaciers other than the Greenland and Antarctic ice sheets lost about 267 billion tons of ice each year. If warming continues, the Earth could lose 68% of its glaciers, a prior study estimated.

In parts of the Andes and other mountain ranges, including the Rocky Mountains, many people depend on mountain snow and glacier runoff for water. It is estimated that shrinking glaciers and snow cover could threaten the water supply for nearly a quarter of the world’s population.

“The vicuñas are probably helping some alpine organisms, but we can’t assume they’ll all be okay, because in Earth’s history, we’ve never seen climate change happen at this speed,” Bueno de Mesquita said. “Current anthropogenic climate change is probably the most severe crisis our planet and all living things have faced in the past 65 million years.”

 

Scientists discover unique microbes in Amazonian peatlands that could influence climate change



Study underscores the urgent need to protect global tropical wetlands from human impact

Complex organisms, thousands of times smaller than a grain of sand, can shape massive ecosystems and influence the fate of Earth's climate, according to a new study.

Researchers from Arizona State University, along with their colleagues from the National University of the Peruvian Amazon, have identified an unknown family of microbes uniquely adapted to the waterlogged, low-oxygen conditions of tropical peatlands in Peru’s northwestern Amazonian rainforest.

The new research shows these microbes have a dual role in the carbon cycle and the potential to either moderate or intensify climate change. This process can either stabilize carbon for long-term storage or release it into the atmosphere as greenhouse gases, particularly CO2 and methane.

Under stable conditions, these microbes enable peatlands to act as vast carbon reservoirs, sequestering carbon and reducing climate risks. However, environmental shifts, including drought and warming, can trigger their activity, accelerating global climate change.

And, continued human-caused disruption of the natural peatland ecosystem could release 500 million tons of carbon by the end of the century — roughly equivalent to 5% of the world’s annual fossil fuel emissions.

"The microbial universe of the Amazon peatlands is vast in space and time, has been hidden by their remote locations, and has been severely under-studied in their local and global contributions, but thanks to local partnerships, we can now visit and study these key ecosystems,” says Hinsby Cadillo Quiroz, corresponding author of the new study and a researcher with the Biodesign Swette Center for Environmental Biotechnology at ASU.

“Our work is finding incredible organisms adapted to this environment, and several of them provide unique and important services — from carbon stabilization or recycling to carbon monoxide detoxification and others.”

Cadillo-Quiroz is also a researcher with the Biodesign Center for Fundamental and Applied Microbiomics and the ASU School of Life Sciences. ASU colleague Michael J. Pavia is the lead author of the investigation.

The study, appearing in the American Society for Microbiology journal Microbiology Spectrum, emphasizes the importance of protecting tropical peatlands to stabilize one of the planet’s most significant carbon storage systems and underscores the subtle interplay between microbial life and global climate regulation.

Why peatlands are crucial for climate stability

The Amazonian peatlands are among the planet’s largest carbon vaults, storing an estimated 3.1 billion tons of carbon in their dense, saturated soils — roughly twice the carbon stored in all the world’s forests. Peatlands are critical for global carbon storage because their waterlogged conditions slow decomposition, allowing organic material to accumulate over thousands of years. These ecosystems play a crucial role in regulating greenhouse gas emissions and influencing global climate patterns.

Building on earlier research, the current study describes newly identified microbes — part of the ancient Bathyarchaeia group that forms a complex network essential to the functioning of this ecosystem. The study highlights the remarkable abilities of these microorganisms to regulate carbon cycling in peatlands. Unlike most organisms, these microbes can thrive in extreme conditions, including environments with little to no oxygen, thanks to their metabolic flexibility.

The microbes are found in the Pastaza-Marañón Foreland Basin — a vital peatland in the northwestern Amazon rainforest of Peru. Encompassing approximately 100,000 square kilometers, the basin includes vast tracts of flooded rainforest and swamps underlain by ancient peat.

These peatland microbes consume carbon monoxide — metabolizing a gas toxic to many organisms — and convert it into energy, simultaneously reducing carbon toxicity in the environment. By breaking down carbon compounds, they produce hydrogen and CO2 that other microbes use to generate methane. Their ability to survive both oxygen-rich and oxygen-poor conditions makes them well suited to Amazonian environments, where water levels and oxygen availability fluctuate throughout the year.

However, shifts in rainfall, temperature and human activities, including deforestation and mining, are disrupting this delicate balance, causing peatlands to release greenhouse gases like carbon dioxide and methane.

Climate connection

While tropical peatlands currently act as carbon sinks, absorbing more carbon than they release, they are increasingly vulnerable to climate change. Rising temperatures and altered rainfall patterns could dry out these peatlands, turning them into carbon sources.

The release of billions of tons of carbon dioxide and methane from peatlands would significantly amplify global warming. The findings emphasize the urgent need to protect tropical peatlands from human activities and climate-induced stress.

The researchers advocate for sustainable land management, including reducing deforestation, drainage and mining activities in peatlands to prevent disruptions. Further investigation of microbial communities is needed to better understand their roles in carbon and nutrient cycling.

Tracking changes in temperature, rainfall and ecosystem dynamics is also necessary to predict future impacts on peatlands.

New directions

The discovery of highly adaptable peatland microbes advances our understanding of microbial diversity and underscores the resilience of life in extreme environments. These microbes represent a key piece of the puzzle in addressing global climate challenges, showing how the tiniest organisms can have an outsized impact on Earth's systems.

This research, supported by the National Science Foundation, marks a significant step forward in understanding the critical role of tropical peatlands and their microbial inhabitants in global carbon cycling. As climate change continues to reshape our planet, these hidden ecosystems hold lessons that may help safeguard our future.

Cadillo-Quiroz and his team plan to use this microbial and ecological knowledge for tropical peatlands management and restoration in their future work, which can be followed here.

“Working to understand microbes and ecosystems in the lush and magnificent Amazon rainforest is the honor of my life, which I aim to use in the protection of this region in the fight against climate change,” Cadillo-Quiroz says.
