Unfortunately, the stable genius in the WH does.
Which part of this is the President "trying" and the Iranians "declining"?

He's probably the only Commander-in-Chief I've had so far to say "I don't think it's proportionate to bomb a bunch of people because we lost a drone."
Iran responded with a carefully-targeted retaliation - a small missile strike against an unused/unmaintained US military installation in Iraq. There were no casualties.
Iran chose a target with low strategic value and no personnel present. Just enough of a strike that they could sell it as retaliation, but not enough of a strike to escalate into a full war.
I won't pretend to know if the assassination was warranted or necessary. But it's easily something that Iran could have used to justify a war.
It's also notable that the USA has also tolerated the Kim regime, because it gives them an excuse to be present in force in South Korea. It's not like the CIA couldn't have the Kims removed if they put some effort into it. PRC would have to pretend to be angry about it, but it would also get them out of the awkward situation.
