ukraine. biden is facing a delicate balancing act and not a lot of evidence he has the savvy to navigate that. on the one hand he needs to show he has the willingness to confront russians in a way that would be sufficiently deterrent but also he can t rattle his saber so hard he risks escalating the situation further and he doesn t on the world stage have the credibility to thread that needle effectively, i don t think. benjamin: you get the feeling the only person who knows what putin will do is putin himself. i want the play something from congressman waltz putin is backing himself in win/win situation. he demands security guarantees where he is dictating the expansion of nato and where we put our troops and our bases, either we pull back from that or he has a pretext to invade ukraine again.
