Might be right, might be wrong — but we have heard this before. Read documents and commentary from the late 1960s and early 1970s. It was chaos. There were riots, the Weather Underground bombed the US Capitol building and people believed society was about to dissolve into anarchy and mass death.
But it didn’t. And that’s mostly forgotten now, even in some cases by people who lived through it.
My personal guess is that we experience a pretty bad WWIII against China, Russia and North Korea, the US pulls together and we and Europe emerge stronger with China diminished and reclusive once again.
But Trump is doing the US much damage that will not be easy to repair. I agree that it is not looking good.
