That's a really simple world you live in. I don't think things are going to wind up the way you do, but only time will tell.
Lots of people share your perspective, but not as many as your bubble leads you to believe. The US has been against the ground war from the beginning, and the world knows it. A UN resolution calling for a ceasefire would be toothless and ineffective, and the world knows that too. It would only serve to undermine the authority of the UN. The ICJ already made demands of Israel (with US backing) and those demands are sitting in Netanyaho's waste basket.
It seems to me that the dollar has been losing its trade status for decades, while somehow never actually doing so. Weird that.
Removal from office takes a supermajority in the Senate, so maybe disqualification via the 14th does as well. That would presumably depend on Senate rules that currently don't cover it.
A simple majority ought to be sufficient, but it also ought to be sufficient for just about everything, but it's not.
