The logistics of moving the men to India, Vietnam, Korea, Taiwan or Japan...is not that much....
What do "we" do? Let them roll in?
Regarding the U.S.A.: it takes money, equipment and resources to move millions of soldiers across the Pacific to China.
Didn't really stop us when we did that to Japan... If it becomes an "existential" war... we can print money like there's no tomorrow.
and that's how empires end... just like everyone before it. Not with a bang, but a whimper.
Let me know when China bombs Pearl Harbor, then I might entertain your idea of sending millions of our soldiers to China. Meanwhile, ain't happening.
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.
