Russia is being sanctioned by every major country. The Ruble is down 40%+. Putin's reputation on the global stage is demolished.
Surely he knew there would be dire consequences to invading Ukraine, and he chose to do so anyway. So either he had damn good reason, or he is retarded. The MSM would have you think the latter.
I'm assuming you are watching legacy news. Trust me, Putin doesn't make a move without planning to the nth degree. You and the rest of us simply don't know what's actually going on in Ukraine. I go to SouthFront to get the Russian side of it, but still am left believing this is a strange dynamic we are observing.
Sometimes I get the sense that Russia (and secretly the Ukraine) are trying to eliminate the Azov battalion and the Bandara worshiping neo-Nazis from the military. If you noticed they are focusing on these units.
Putin said he would denazify Ukraine. I think you are on the right track.
