This is history as geopolitical vendetta tool. Your grandparents and my grandparents may have known each other. My paternal grandmother was born in Vinnitsya and got out in 1921 with my grandfather who had served in the Jewish brigade of the Briths Army in Palestine and went back to get her. He was born in Chmelnik and grew up in Kishinev, living through the 1903 pogrom. So I have as much reason as you do to write the same. Why don't I? Because holding a 20 or 30 something Ukrainian responsible for his great-grandparents' anti-semitism makes no sense. It's branding a people with illogically essentialist collective guilt. Since I live in Latvia, I'm quite familiar with east European anti-semitism. But both Latvia and Ukraine have elected Jewish presidents.

Your last paragraph also makes no sense since Ukraine isn't in NATO and it won't trigger Article 5.
