I am convinced that Israel has realized that it can't survive a drawn out conflict, and will endlessly provoke literally all of it's neighbors until things have escalated to the point that the US feels the need to properly enter the fray.
Edited: Bad wording on my part in the first one. I'm just tired - not awful
I recently saw polling that showed the majority of Americans oppose sending troops to support Israel.
So, yeah. If US troops are deployed in the region I'd expect the homefront to become a problem.
