more sanctions and more resistance, that might deter putin. but he seems very intent on following through with this plan. many of us in the military have been surprised how long it has taken to unfold, how slow the russians have been to move. but there's probably concern on the part of the russian generals, not on the part of mr. putin. the russian generals built these forces. they know they will go against heavy ukrainian resistance. they tkroef the air power the russian defense do, but the ukrainians have their own land they will fight for. i think we are seeing caution preplanning by the russians at this stage. mr. putin, he believes time is on his side. he's trying to pick apart the nato allies. he hasn't been successful. at some point he will launch forces.
