I haven't seen a lot of Taiwanese defending the US against its invasion by Mexico.
In Korean thing, Taiwan offered to send 50,000 men to fight the Chinese reds. Truman turned them down so 40,000 Americans died. Some were my friendds and comrades.
MacArthur wanted to march to Peking and wipe them out.
Remember that Cyni was in B-29 with all the gun mounts removed except for tail gunner. If the order came they were to fly north with their payload. I believe this was after MacArthur pulled off Inchon. The order never came. ;)
