Would it? Is that even possible with every last member of Congress already bribed or threatened by Israel?
The only way I could envision the US cutting off Israel’s funding is if there was a law requiring Congress people to wear exploding neck collars that were triggered by a polygraph machine and they were required to state each hour of the day that they, nor any family or friends had accepted any bribe from anyone directly or indirectly connected to Israel or any past or present Israeli citizen.
Maybe…we could recover 10% of the Congress. The other 90% are so accustomed to lying that a polygraph would probably detect nothing.
Instead of playing “whack a mole” trying to sort out the compromised officials in the US, it makes much more sense to just obliterate Israel completely and cure the problem at the source. Once there is no more Israel, then there is no more need to find all their spies and counteract all their subversion.
