Given that the very real issues America faces actually relate to becoming a more pragmatic, fact-based, reasoned place, what do you suggest? The 21st century is decidedly not the 20th, even if it may face similar dangers, or worse. Trump is the imaginary Maginot Line against the dangers of the world. We all know how fighting and working on yesterday's assumptions can lead to catastrophic failure.
The game is geopolitics, power the currency. This currency is backed by cash and influence, only partially by muscle. Cash accrues best to those with large internal markets from which to gain the production volume and economies of scale in innovation and research to outcompete others. This is what the USA did in the second half of the 20th century. This is the 21st century, the largest market is no longer the USA, that old motor will no longer win all the races, even not for lack of trying. That new world is a result not just of trade agreements good or poor, but from contemporary market structure.
Now, USA, plan your future. My guess is that you could use friends of similar mind, exactly those you plan to push furthest away right now, exactly those who are in shock.
