The Biden administration said Friday that Israel’s use of U.S.-provided weapons in Gaza likely violated international humanitarian law but that wartime conditions prevented U.S. officials from determining that for certain in specific airstrikes.

One of the key voices in this matter is Josh Paul, a former director at the State Department’s Bureau of Political-Military Affairs, who resigned in protest after October 7, accusing the US of ignoring a “wider body of rules” within its own domestic law when it comes to arms sales to Israel.

It’s the bluntest articulation yet from a Biden administration official that Israel can’t succeed at its goal of wiping out Hamas.

Army Maj. Harrison Mann, a Middle East analyst at the Defense Intelligence Agency, is the first military officer known to have cited U.S. support for Israel’s war as the reason for resigning.

Israel began toned down Independence Day celebrations at sundown on Monday, with hopes for an end to the seven-month-old Gaza war dim, anti-government protests growing and internal divisions festering.
