Without the say-so of the US Congress, or the Israeli Knesset? You must think that the Israeli Prime Minister's powers are a bit more unilateral than they actually are.
But thanks for playing.
The US Congress would not force aid onto Israel if the Israeli government said it didn’t want it.
If Netanyahu didn’t want aid he would ask the Knesset to discuss whether it should be accepted. With 120 members from 13 parties in the Knesset and this crazy proposal never coming up for discussion, it should be obvious that your anti-Israel idea has no support within that country.
