I believe the U.S. will help Taiwan fight, because Americans hates Chinese. In my 40 plus years living in the U.S. tells me that. Hollywood always portrait Chinese as bad and evil people, especially when Russia is no longer a threat to the U.S. so creating a imagery enemy is important for military purpose. Also Americans think China is a paper tiger just like 1800's when 8 nation ransack China. The second coming of Yellow Peril is the deep fear shared by European and Americans. Some of you might not know what I am talking about, but when Gangus Kahn swept through Europe back in the Yuan Dynasty was the first Yellow Peril. If we look at the Chinese culture from a bird eye view, than we are on the wrong side of history, but it is what it is.
