We aren't even fighting. We're just giving essentially token moral support.It is not our fight to fight -
But it's also wrong to stand back and watch.
Russia is not going to start shooting down NATO aircraft. That would be a clear escalation and would brook reprisals. Russia must know that they can't win this war if it escalates, they are far outmatched by NATO. Any overtly hostile action against NATO will lead to rapid demilitarization of Russia using conventional means. Russia, if it were wise, would try wrap this up keeping Crimea. They are in danger of losing that strategic position. The longer this drags out, the likelier Putin is to suffer a coup.
