Putin may have been tempted, lured, baited or even duped into invading Ukraine. He may have been lied to by his own generals and spymasters. He may not be the grand strategists so many thought. But he alone pulled the trigger. His tanks crossed the border. His bombs destroyed city blocks, hospitals, train depots. His army is occupying foreign ground. Excuses can be made. But they only mitigate his crimes, they don’t exculpate them.
