Wouldn't be the first time I was fooled, and it's always hard to make predictions, especially about the future (as the joke goes). I deliberately tried for more specific predictions than I made about Dubya early in 2001, but the more specific, the less likely they will be fulfilled. As regards those three predictions, you may notice that the premises are actually quite conservative and safe, but the conclusions could easily get derailed in a number of ways.
Just to focus on the first prediction, as regards the premise we know that Trump has promised to put pressure on foreign countries and has already said a number of provocative things to and about China. Though he lies a lot, I think he is mostly sort of sincere on hating his business adversaries. Now will China decide this represents an opportunity to get Taiwan back? Hard to say, and if so, will they decide that a military approach is feasible? Again hard to say, but if they are leaning that way, then creating the diversion in North Korea is obvious... It should also be obvious that the Chinese dictators would love to scapegoat Trump for their own economic mistakes and real world limitations, but the devil is in the details, as they say.
I actually sort of agree with you about "improve [the] lives of Americans", but NOT the way you probably meant it. I think he is going to make certain rich people much richer and they will think that is improving their lives, even though they already have far more money than they will ever use. Your other quasi-prediction of "unnecessary conflict" seems basically meaningless, since he is already creating plenty of conflict, but it must be "necessary", eh?
Hey, does the stock market need to have any relationship to reality or is the entire value just a matter of #PresidentTweety's opinions?
