Biden is playing American "Good cop to Yahu's Israel's bad cop".Biden is trying to de-escalate things, on the other hand as you say, it's an opportunity to take out Irans nuclear facility and it's drone building facilities. Doubt anything will happen before the UN meeting.
Just in case, you should buy bottled water and feed the cats.
They are a double act.
Biden wants to keep the anti Israel factions in his party onside while appeasing the pro Israel factions by saying he supports Israel 100%.
