No it was called a Police Action, and you can thank Harry @ss Truman for the defeat and loss of lives. He also gets credit for the survival of Mao.
Thanks, but I'll stick with "Korean War" - euphemisms and distinctions without difference just don't appeal to me. I'm aware there was no formal declaration of war.
I don't give Truman a pass over the outcome, but he didn't send 200,000 chinese troops into Korea, China did; so I still consider China to be ultimately responsible for the survival of the Norks, then and now.
