I don't think the first group understands how important Europe is to America's status as superpower, while the second group operates under the delusion that the world will go back to business as usual after the next presidential election.

Only the elderly who are blind to the decline and can’t even picture a world order outside other than Pax Americana believe we will go back to business as usual. The rest of us realize it will take decades of stability to gain a semblance of the trust we used to be granted. And in the mean time the rest of the world will forge ties that don’t include us. We will be weakened on the world stage compared to status quo prior to trump for the rest of my life I’m sure.

You think there's gonna be a next one? He's installed his own people in all the right places, and got his own Praetorian guard.

Plenty of us in the second group don't think the world will go back to business as usual.
