Democrats for Israel California strongly supports Iron Dome funding. Iron Dome is an anti-missile system which is a critical defensive measure against Hamas' rockets. After the most recent Hamas attacks of nearly 2,400 rockets, President Biden pledged to replenish the amounts in a supplemental appropriation. The attempt to pull it from the Debt Ceiling/Continuing Appropriation will not prevent the funding as Appropriations Chair Rosa DeLauro has already introduced legislation to provide the funding and unlike the Debt Ceiling (which Republicans repeatedly try to turn into a partisan issue and it always backfires), the DeLauro bill will have strong bipartisan support as Israel has enjoyed for decades and will continue to do so.
It is telling that the Congressmembers who opposed Iron Dome funding are choosing a defensive tool that protects against a Hamas and Hezbollah attack tactic that has been repeatedly cited as violating international law. Unlike JDAMs (guided missiles that explode underground to target bunkers and tunnels), Iron Dome is a purely defensive weapon and U.S. security aid is a critical part of Israel's military advantage. This year's total US security assistance to Israel is about equal to approximately 4% of Israel's total annual budget. It is also telling when any member of Congress puts this sort of issue ahead of funding the U.S. government.
At the end of the day, this is meaningless empty action, as are Republican attempts to politicize the issue as they oppose the Debt Ceiling Bill either way and have already voted against appropriations bills funding Israel three times year.
