China has done an awesome job in building a military that can win a war for Taiwan. They have a very strong integrated air defense system, enough short range missiles to effectively deny the South China Sea to surface vessels and enough long range missiles to crater all of the nearby airfields the US would use in any such conflict. It's not clear they could successfully invade, but can they sink any ship bringing food into Taiwan? Probably, and realistically that's all they need to do to win.
On the flip side, what can the US do to get China to stop fighting if they don't want to give up? An invasion couldn't possibly take over the whole country and might trigger a nuclear reprisal, a blockade would take longer to work against China than Taiwan, and the economic consequences would hit the US quite hard. How many Americans want to buy war bonds and go on rationing to protect Taiwan? Especially with the current political polarization?
I don't think it's a sure fire win for China, but it's already in the realm of plausibility.
