Are you paying and coordinating? I think you don't understand the logistics of moving men and materials during war. Estimates are that it would take China several months to slog their way towards the capital of Taiwan, and that's if they manage to land at the shore of Taiwan. Logistics are difficult. Even more so if China were to attempt to send troops to the U.S.A. across the Pacific. Ain't happening.
I agree with you. The next war will between the super powers will be electronic and biological. The brute force will be for regional conflicts.
