Let's say good ol' Red China invaded Taiwan/Formosa in the 60's and, for whatever reason, the Americans decided to stay out.
My three questions are:
1. How long would it take, roughly, for the invasion to succeed?
2. What would be the political consequences of US government neutrality (verbal condemnation but no substantial action) at home?
3. Would resistance to the PRC in Taiwan be significant? (It's my understanding that Chiang Kai-shek and Co. were not liked by the actual Taiwanese)
