hungary, czechoslovakia, rather czech republic, slovakia, other countries that did enter nado, romania, bulgaria, etc., that they sort of work that out better than ukraine did. and ukraine was a problematic in that regard. but i probably the ultimate answer and it's very frustrating to state from a ukrainian of view but the ultimate answer is the proximity to russia and that the baltic republics other on the map, they're not further from russia then than ukraine is. they felt in some ways further from russia non slavic populations, predominately not orthodox christian. however you wish to sort thematic these things perhaps perceive as more european than ukraine, but the sense that ukraine was somehow tied to russia i think was very problematic. the western europeans and others who are contemplating membership in nato's in the eu that of course looks very different in the hindsight the last 12 months. but i think that that was an important part of the story in the 1990s and thereafter. well, i would like to thank for your wonderful questions and to thank this audience and our other audiences thei
