True. I would argue that Taiwan cannot stop China from having a successful invasion. They can only make it so costly that China would not be willing to pay the price. Both in manpower and political blowback.
So I’m not sure how real is China threat for East Asia.
If you look into their history, stable China always translated to stable East Asia.
I’m really worried about all these trends and military moves on that region. We might make East Asia the next Middle East. Not to mention once it happened to them during the colonization and it took them ages to recover.
