Democratic progressives are attempting to reset the traditional bipartisan U.S. support for Israel, though real policy changes will have to wait for future U.S. elections in 2022 and 2024 that could produce enough progressive seats to force deeper changes to U.S.-Israeli relations. House Democrats stripped a $1 billion provision to resupply Israel's Iron Dome from the U.S. government's funding package Sept. 21 after progressive Democrats opposed to the provision threatened to withhold votes for it. This was the second time the same group of Democrats has attempted to block U.S. aid to Israel: In May during the Gaza War, the same caucus attempted to block a $735 million sale of U.S. precision-guided weapons to Israel, though the deal ultimately went through.
