By enlisting North Korean combat troops in its invasion of Ukraine, Russia has invited NATO troops to do the same on behalf of Ukraine. Russia's action constitutes a significant escalation of the war and nullifies any complaint that Russia might otherwise have against the introduction of NATO troops on the ground in Ukraine. It would also justify South Korea sending at least the same amount of troops that North Korea sends.
