They both had troops in China and were heavily invested in the war, and when I mentioned if you knew the world situation, it was about the high war tension on the Korean border and in Europe with Russia, those two hot zones occupied most of our military.
Your use of the word “easily” was not a good choice and what I was pointing out.
Like I said, the USSR and China turned on each other and were in no position to fight a war with the US, they were invested in the outcome and invested all their efforts in winning the war by sabotaging it from within the US.
