The missiles in question were using U.S. tracking with U.S. personnel, also what Russia was trying to eliminate is the possibility of a false positive on a nuclear strike i.e. WWIII. The U.S. has been at war with Russia since the fall of the USSR, they just weren't going to allow it to progress further in that area. Not complex, you can disagree.... I guess but its not material at this point.
For the record, I don't know if North Korean troops are used, and it doesn't seem material to the U.S. or the discussion, imo.
There are only two real choices for the Orange Man 1.) keep the scam going or 2.) stop the scam... there is nothing else. The scam was going to end shortly under Biden or Kamala as well, probably time table is being sped up.
(the real quote is actually a little different but this one still hits the mark)
