Back then we had the Soviets. We didn’t really have anyone to worry about the past 30 years. Now would be a good time for China to seize Taiwan. Let’s be honest. Will our navy be able to beat China? I think that’s going to be a question mark. 5 years ago, I would say no way because we are that much more advanced. But we’ve gone insane since then so China would win by default (assuming nuclear weapons are off limits).
