Once again, your argument is in favor of not helping the Allies against the Axis powers. This is not about democracy promotion. It's about repelling an invasion from a dictatorship. Invading a nonexpansionist Third Reich is a different proposition from helping other countries fight off an invasion from a Morgen die Welt conqueror. As I said, I agree the US shouldn't install and prop up illegitimate governments like the RVN. The people ruled by the illegitimate government won't appreciate it. That's not what's going on here.
