ukraine -- steven pifiver is noa william perry fellow at stanford university. mr. ambassador, thanks so much for your time. what is your read on put upon's move? peacekeepers? or essentially, potentially, partitioning part of a sovereign nation? >> well, he definitely hasn't violated international law and numerous commitments that russia's made both to ukraine but also international documents by this move, which basically ignores ukrainian territorial integrity and ukrainian sovereignty. but i worry a little bit more -- going back to the speech that mr. putin made last night -- which, um, goes beyond a justification or recognition of the two little states -- the two little people's republics but it looks to me like it was actually laying out a list of grievances -- many of which are not base in fact -- for perhaps a broader attack on ukraine,
