this is part of a broader foreign policy issue for this administration, michael? >> brett has a way with words but i think he has sort of a very solid point there which is, you know, we talk as we discussed last time, we talk a lot about norms and principles. we talk a lot about deescalation. we don't want to see the situation in ukraine erupt into further violence but basically, principles have no meaning if you don't act on them. deter ens doesn't work without action to show countries like russia that you're serious in your willingness to commit further resources, further force to your policy there. and right now, i think there's a credibility problem. you know, does russia really believe us when we say that we'll increase sanction or say we'll take more serious steps or do they think we're prepared to put commercial interests first or to really sort of walk away from the region once it drops out of the headlines? committing moscow requires action, not just words. jenna: and that's the question, what further action are we willing to take. thank you. >> thank you. jon: fo
