Isn't the US already doing this all by itself with Trump at the helm?weaker alliances
I fully believe this can happen any time. I think race relations are a huge problem and it hasn't gotten any better. If anything, given everyone has a cell phone and camera these days, we are shown over and over again how much of a divide there really is.massive civil unrest in the United States.
I have been saying over and over again that going forward, the job situation just doesn't look good at all given all the automation just on the horizon. When poor people lose their livelihood, and you have the rich getting even richer at the same time, civil unrest gets more and more possible. With technology these days, its even easier to spread the word and organize.
I agree that the US wont be beat on a military front any time soon, but the problems from within I think are almost guaranteed going forward.
