Bibi, apparently, is back. Hot damn! Just what we need: a norm-breaking right-wing populist who wants to conspire with the GOP to force America to bomb Iran. Don’t we have better things to do right now?
Mostly fortunately for us, the world has changed significantly since Bibi left office. America is already very busy dealing with Russia and China. Israel and Saudi Arabia have an evolving, de facto alliance; neither has done anything for us with Ukraine. Finally, the ayatollahs are in trouble in Iran. There is no way Biden is either going to sign an agreement with the Iranian government or send in the bombers as long as a reasonable possibility of regime change exists.
I think the bottom line here is that events are driving us to disengage from the Middle East. I suspect Biden will tell the Israelis and Saudis to deal with Iran by themselves. We can only fight so many wars at one time.
