Putin is singularly the one to blame for starting the conflict no doubt. I don’t really care what sort of grievances he had against Ukraine, but for over a decade he has directed and funded insurrection in eastern Ukraine leading up to this and it is clearly a war for territorial expansion. I don’t really give a damn about expanding US and NATO influence, most of that was likely brought on by a reemerging and outward looking Russia with a president looking to rebuild the USSR. As great as it would be for Ukraine to win, this isn’t Hollywood, and the good guys don’t always win. But we can stop them from ceasing to exist if they would face reality.
