Would there have been a conflict between opposing war against Nazi Germany and being Jewish? (Rhetorical question, yes, but very pertinent because both Nazi Germany and the Islamofascist axis have as proclaimed goals the destruction of the Jewish people!)
A great many Jews in 1930s America opposed war, as did most Americans. They didn't feel it was in America's interest. Other Jews pointed out the evil of Hitler, and suffered the typical conspirital accusations of anti-Americanism. Things don't change. It's not a Jewish thing.
Good point. The danger from the Nazis was more acute because they were killing Jews, en mass, during the war. The Islamists do not have control to do so, but should
they ever get control or Nukes they certainly would kill as many Jews as possible.
