My 7-yr-old daughter is in Ukraine visiting grandparents, for a few more days, so I've been reading rather than posting on the subject.  This article by George Woloshyn in the Kyiv Post makes a very good case for Ukraine joining NATO, and quick – strength is the only way to ward off bullies.  [I corresponded with the author some months ago regarding Solzhenitsyn's denial of the genocidal nature of Holodomor, which we both agree was reprehensible.]
