"I once thought that I was a freak," says Rabbi Refael Kruskal, the vice president of the Jewish community in Odessa, a port city in Ukraine. While many others in the country doubted the prospect of a Russian invasion, Kruskal -- the son of a Holocaust survivor -- took his cues not from the headlines but from Jewish history. "I had supplies on trucks. I had generators prepared. I said there’s gonna be a rush on gas stations, so I had gas prepared for the buses on the way." He ended up needing every gallon.
