The United States has quietly approved and delivered more than 100 separate foreign military sales to Israel since the Gaza war began Oct. 7, amounting to thousands of precision-guided munitions, small diameter bombs, bunker busters, small arms and other lethal aid, U.S. officials told members of Congress in a recent classified briefing.

The triple digit figure, which has not been previously reported, is the latest indication of Washington’s extensive involvement in the polarizing five-month conflict even as top U.S. officials and lawmakers increasingly express deep reservations about Israel’s military tactics in a campaign that has killed more than 30,000 Palestinians, according to Gaza’s health authorities.

Only two approved foreign military sales to Israel have been made public since the start of conflict: $106 million worth of tank ammunition and $147.5 million of components needed to make 155 mm shells. Those sales invited public scrutiny because the Biden administration bypassed Congress to approve the packages by invoking an emergency authority.

But in the case of the 100 other transactions, known in government-speak as Foreign Military Sales or FMS, the weapons transfers were processed without any public debate because each fell under a specific dollar amount that requires the executive branch to individually notify Congress, according to U.S. officials and lawmakers who, like others, spoke on the condition of anonymity to discuss a sensitive military matter.

What is clear is Washington’s deep involvement in the conflict, even if it isn’t the entity dropping the munitions or pulling the trigger, said Konyndyk, the former administration official.
