Maybe hypothetical other presidents would have done all the same things, but Joe Biden has personally made active moves to support the genocide. “We sent them billions of dollars a year that built a war machine itching to be used” is an America problem. Biden’s proactive actions to arm them and defend them from consequences is a Biden problem.
And protest actions (and the general polling that’s a follow-on to activism not letting the issue fade away), is part of why Biden is slowly turning toward a harder and more humanitarian stance. None of this has ever been about choosing between two people for the next genocide response, it’s always about making him change course NOW.
