Some people think it goes to nukes immediately. I don’t think so. It will stay sidelined like chemical weapons that were used in WW1 but avoided and unused in WW2.

The US does not have the industrial capability that it once had and has struggled with manufacturing of electronic components. Now maybe that can be changed, but maybe not fast enough to matter. But as far as current capability they got combat experience and are the only nation that has proven ability to project military power worldwide. As long as logistics keep up they can kick serious ass.

China makes a ton of stuff already, and that would make a hell of a wartime production rate that can scale too. Their military is untested, but large, new and growing. They are the gorilla in the room. Hell they might think Russia is the easier fish to fry and take them on first.

But there’s also the chance of everything falling apart where most nations desintigrate into a long term state of fracture with infighting and homeland problems overriding any possibility of winning a global fight, and therefore preventing a large world war like we’ve seen in the past. Rand calls it neomedievalism
