A new report by Brown University’s Cost of War Project has revealed that Israel’s war on Gaza was heavily dependent on US financial and military aid, with Washington spending over $21 billion to sustain the conflict.

The findings come as Gaza authorities release devastating figures on casualties and destruction caused by Israeli attacks.

US spent $21bn supporting Israel’s war in Gaza

According to the Brown University report, the United States spent a staggering $21 billion during Israel’s military campaign in Gaza. The report states that Israel “could not have fought the Gaza war without US support,” underscoring Washington’s central role in the conflict.

The US reportedly supplied $8.12 billion worth of weapons and $5 billion worth of defense systems to Israel during the war. In addition, another $4.4 billion worth of weapons were provided directly from American military stockpiles.

Gaza authorities detail humanitarian catastrophe

Meanwhile, the Gaza administration has released harrowing details of the humanitarian toll of Israel’s attacks. According to their data, 67,173 Palestinians have been killed in Israeli bombings since the war began.

The report adds that 1,701 medical workers were martyred, while 362 others were arrested by Israeli forces.

Food shortages have also taken a deadly toll, with 460 Palestinians, including 154 children, dying of hunger, according to Gaza health officials.

Health system on brink of collapse

Gaza’s health infrastructure has been devastated by months of Israeli strikes. Authorities reported that 25 out of 38 hospitals have been completely destroyed, while 103 out of 157 primary healthcare centers are no longer operational.

Due to overcrowding and resource shortages, hospitals are now treating more than two patients on a single bed, painting a grim picture of the region’s collapsing medical system.

US role under global scrutiny

The Brown University report has reignited global debate about the United States’ role in the Gaza conflict, with analysts arguing that continued military support directly enabled the scale and duration of Israel’s offensive.

The Cost of War Project, based at Brown University’s Watson Institute for International and Public Affairs, has long examined the human and financial costs of global conflicts involving the US military.
