China doesn't have the amphibious capability to invade. Yet.

You must assume that the Chinese military has some of their smartest people thinking about unconventional ways to invade across water, which would give little advance warning of the pre-invasion buildup. Merchant ships, inflatable speedboats, blimps, quickly modifying passenger airliners for paratrooping, whatever. Do not assume they don't have some potential surprises up their sleeves

China is a very patient country. I don't see them invading as long as they believe that eventually Taiwan will choose to join the mainland.

However, it's important to deter them, just in case.
