probably something on the order of -- it doesn't have to be lethal. ukrainians are conducting defensive operations against a massive force. so provisioning them with logistics, establishing a pipeline to provide that, i think the sanctions probably are okay for where we are right now. there's a lot more head room for action. i think positioning forces make a good buit of sense. i don't think we did enough to deter russian aggression early on. frankly, i think we're going to look back on. as a meaningful misstep is when president biden said we will only defend nato. that in a way offered a green light to putin to conduct this operation. >> we did not have to contend the ambiguity of a nato and u.s. response. we have the policy of strategic ambiguity for a reason.
