and as you point out, bill burns, who was then the american ambassador in moscow, he told condo, lisa rice, who of course, was secretary of state that ukraine and nato was the brightest of red lines for the russian foreign policy elite. he made it very clear that this is not just include vladimir putin, virtually everybody he talked to in the russian. a lee was adamantly opposed to ukraine, becoming a member of nato. nevertheless, we continue to push to include ukraine in nato, and that led to the message that we're in today. and this is why i say that the united states and nato more generally, is principally responsible for creating this crisis. had we not pushed to include ukraine in nato in april 2008. if that issue had been taken off the table, then we wouldn't have the trouble today. in fact, ukraine would still be intact and i believe it would even include crimea. now you are a famous realist and realists are have an adage which is you've got to see the world as it is and not the world as you want it to be. and the world as it is today is millions of ukrainians have been displaced. m
