Probably get hate for this around here, but it would be pants-on-head retarded for a political candidate to propose a major policy shift 3-weeks before a national election.
Lots of people said that about switching candidates just a few months before the election but they pulled that off fine. Abandoning a pro-genocide stance seems like a low bar in that regard.
Do you think the morals of 1 person runs the USA? Because it doesn't. Oil money runs the USA. America wants to build an oil pipeline and that pipeline cuts through Gaza and the West Bank. Trump will simply divert funds from Ukraine and give to Israel.
It'd be genius, if anything. Soon enough that people will know it and vote for her (the majority of Democrats support conditioning Israeli aid), too late for AIPAC'd propaganda machine to push the election towards Trump.
