tit-for-tat? About 8,000 North Korean troops at Ukraine’s border are expected in combat in days, US says

AP, About 8,000 North Korean troops at Ukraine’s border are expected in combat in days, US says,  If NK troops fight in Kursk for Russia, why can’t NATO troops fight in Ukraine for Kyiv? Simple: it may look as though NATO troops killing Russians and vice versa is the same as Ukrainians killing North Koreans and vice versa, but it only looks that way if one fails to appreciate the distinctive character of the nuclear superpowers and their relationship. Putting additional NATO troops in Ukraine (beyond the ~100 already present) is qualitatively different. Putin has found a way to match NATO brinkmanship. For now.
