One should also remember that Ukraine had been part of Russia for virtually its entire history. One should also remember that it was the Russians who defeated the Nazis (if you look at casulties on both sides, arguably the Anglo-American western front was a “side show” compared to the Eastern front), and that the Ukrainians were among the most notorious as collaborators. That the “liberal” Ukrainian coalition includes some groups that are clearly fascist, and includes others with a solid history of corruption and incompetence (which is how Ukraine fell behind Russia in the 20 years they have been separate countries).
While the United States for reasons of geopolitics should probably be supporting Ukraine, from a Jewish perspective, Jewish neutrality is probably the best policy.
