The kal shoot down wasn’t during the Korean or Vietnam war. You still haven’t provided examples to back up your claim
You’re telling me you’re so lame you can’t Google this?
Geez.
https://en.wikipedia.org/wiki/Soviet_Union_in_the_Korean_War
IN THE VERY FIRST PARAGRAPH:
“Though not officially belligerent in the Korean War (19501953), the communist Soviet Union played a significant, covert role in the conflict through its provision of material and medical services and also Soviet pilots and aircraft (most notably MiG 15 jet fighters) to aid the North Korean-Chinese forces engaged in combat with United Nations Forces.”
Like I said, these are established and known facts. Now go look up the Vietnam info on your own. It’s there and if you make me look it up for you I’ll mock you again.
