And Trump has assured everyone we will "get the dust" so many times that he can't accept less either. Really hard to see an endgame here. Don't think getting it militarily is an option- the base where the dust is buried is on the outskirts of a city of 1.5 million with two IRGC divisions. And it would take two weeks to dig it out. Don't think even Delta Force could survive that.
$20 billion in unfrozen assets, sanctions removed, no blockade and no power plants bombed. I expect even TACO Trump will get around to bombing those eventually.
