The reality is that Russia invaded a sovereign nation. However, that nation never joined any military alliances. So we are not going to defend them.
What seems evident however, Russian special forces are getting their ass kicked in Ukraine and the general troops coming in behind are going to get wiped. Russia is about to come up against general mobilization of highly motivated VERY well supplied freedom fighters.
I'm also pretty convinced there's massive degree of proxy war going on. Everyone's special forces are in ukraine wiping Russians off the map. Everyone has basically declassified Russian troop movements. The Russians can't win.
When a country starts a war like this and after only a few days of losing spectacularly... they call for peace talks. They know they screwed up pretty big time. Russia will be paying for this for a long time.
