I tend to agree and have tremendous concern for my son and grand kids who will face a degree of hardship that is difficult to imagine for the great majority of people.
Once Globo-cop is off the beat, I could see China annexing Hong Kong (and maybe killing 1/2-3/4 of the inhabitants in the ensuing unrest) and Taiwan (and killing 1/2 the Taiwanese in the attempt).
Pakistan and India may throw down again.
The Arabs, if they can coordinate policy long enough, may take another swipe at Israel (once the US can no longer bankroll Israel).
Then, Russia invading and annexing Belarus, Ukraine, Georgia.
Serbia annexing the Republika Srpska in Bosnia-Herzegovina.
Heck, even Mexico trying to recover Texas and California if the US are screwed up enough.
It is going to be a sporty world.
