Smart people.If Taiwan fall,Japan could be next,and after that India end sanwiched between China and Pakistan.Get India to join in defending Taiwan and China is fucked. Inda sits alongside their primary route from the Middle East. War starts? India can cut the flow of crude to China.
From Chineese point of viev,India is only place where their 100 million young man without wives/becouse they get killed as unborn children/ could get their womans.
And if some of them die in process - even better.
