The US can't force Israel to do anything. They are a reasonably wealthy state with significant military prowess and supplies in their own right.
I keep seeing this narrative here on the fediverse that somehow it's all Biden's fault because if we didn't send them weapons, the whole thing would be over. It's just false.
We shouldn't send them weapons, but stopping doing so would not stop the genocide.
No, they wouldn't have. Israel has an impressive military of its own.
