If Israel wants peace, there’s not much the US is going to do to force them to keep fighting.
But there are explicit things the US can do to stop them from continuing their genocide.
All indications are, in-fact, the US is the only group that can actually stop the war and the US doesn’t need a ceasefire to do so.
We have previously conditioned aid to Israel to yank the choke collar, and it has proven effective. The only reason the US has not done so in this conflict is a lack of will.
