Re: Putin is not Trump
It won't be Russia vs America, because Trump likes Russia. He's making noises about reducing NATO, which would let Russia extend into Europe and eventually Britain or France might fight back with nukes, but that's a whole other scenario.
It is China that Trump dislikes. He's already "pissed them off" by accepting a phone call from Taiwan, and they've already retaliated by grabbing a US research drone (from the sea). If that kind of thing escalates, there's no knowing where it will stop. China owns vast amounts of US debt, for example.
