"There's a 100% chance of some sort of conflict between the US and China over Taiwan [etc]" Yes, it's happening all the time along with several other conflicts. However it is not WWIII as envisaged by OP or me. WW3 is what I and anyone else aged around 50+ worried about in the '50-'90s and it was a sort of W Europe + US n that vs the USSR and that and would involve tactical nukes to start with and then go strategic or vice versa (without the versa.) The sort of conflict that might spring up between the US and another nation in a major way over something is a bit undefined at the moment. It might involve the USMC and a carrier group or whatever or something else. Perhaps we could get PotUS to play Top Trumps vs Pooh Bear. I don't know but I am fairly sure that nuclear is still off the table. I think you might be right about space: willy waving with minimal personal danger sounds about right.
