Ireland is, and has been, the most antisemitic Catholic nation in Western Europe, and that's really saying something. During World War 2, The Republican of Ireland was on the side of the Nazis, lol.
Ireland was officially neutral during WWII. It covertly supported the Allies in many ways. Dev did offer condolences on Hitler's death, but that was out of protocol and the difficulty of maintaining neutrality under external pressure. You won't last long in this community misrepresenting facts that are so easily verifiable.
