“The US engaged Russian fighters in both North Korea and Vietnam”
When and where did that happen? Were there dogfights? Shooting exchanges on the ground? Please provide evidence for this claim. Links, please.
The truth is, in Korea Macarthur wanted to fight the Chinese - and Truman fired him out of feat of WWIII. Truman would have fired the wild-eyed Fiorina too.
It’s kind of interesting that both of you seem to be ok with US getting into another Korean or Vietnam war, in Syria. If Fiorina keeps talking this way, and somehow gets nominated, look for a national loss of even greater proportions than he California flame-out against Boxer.
The facts are sufficiently documented that I don't need to do anything. Go educate yourself and you'll find the information you seek in lots of places, like your public library.
