If it comes down to it, no asian nation can deny the US from forcibly invading and making their country into missile bases against China. Dont delude yourself thinking you can resist the US, or that your government, that will be heavily pressured by the US at that point and/or sanctioned to hell, WILL EVEN WANT to resist.
This will be like Belgium during the Nazi Invasion of France all over again.
You cant stop it, you cant fight it, and the US wont care if they have to murder millions of you and take millions more of you hostage to make your country into their staging ground.
Sorry if this sounds harsh, but when great powers fight, there is no mercy for the small guy. Especially not if this is a fight for the survival of american hegemony; something on which the living standards of 300+ million US citizens vitally depends on every single day.
Someone needs to convince the Taiwanese that they are only needed by the west to absorb Chinese/western munition to protect western interest in the pacifi. All of this has basically public said by generals, politicians and think-tanks in regards to keeping China surrounded in the first island chain. Maybe they will actually flip if they knew the real truth. Maybe some can say the CCP rule is not the greatest, but it is a lot better than your end goal of being just canon foddler
