Even if we threw everything at it and turned it into a war economy making everything to focus on this task, we'd lose most of our influence in the rest of the world at that time and then we'd end up in a Russia situation once we control the land where we are in a non stop war with people dying the entire time we are there. There's no situation where it makes sense for us to do this or to have attacked Iran in the first place.

Yeah it's stupid, though with this administration stupid seems to be the flavor they prefer.
