I guess shells are in high demand, currently. I don’t expect much but I hope the Senate votes it down or removes the majority of the Israel aid package. Currently it’s about 12 Billion USD worth of various support in addition to 14 Billion “Unconditional Military Support” while dealing with Iran.
If I had to rationalize it, I expect they simply want to give the bare minimum to avoid requiring sending soldiers to invade Iran directly. In my opinion, we’d be justified to “invade” Israel and oust the Netanyahu administration, solving the entire problem a lot cheaper.
