Are Ukraine Jews anything like American Jews? I mean, is it too broad a term to be of much value? Do opinions pretty much shape around politics and the Jew part bows to that? I really don’t know.
I am not sure there are a whole lot of truth tellers in some of these situations.
Ref your question on commonality between Ukrainian and American Jews: My research has not addressed this specifically. In a general sense, there has always been the politics of survival for Jewish communities living as small minorities throughout the world. And there are always portions of every community(Jewish & Gentile)who subordinate their religious beliefs to their political beliefs. My observation is that this is far more common for those on the political left (this includes all varieties of socialists).
