Vastly. I mean, it's hard to imagine how to conceptualize how you would bring Ukraine into NATO while it has a hostile relationship with Russia. In fact, a portion of its territory is occupied by Russia or its proxies in the Donbass, and then there's the whole issue of Crimea. I guess, to be literal, that if we brought them into NATO we would immediately go into war-fighting mode to defend the Donbass and to buffer off the Crimean peninsula. We'd go into war mode if we actually brought them into NATO.
