And could you maybe help me understand why your sense of Nationalism is different from the Nationalism that Hitler strengthened and exploited?
As for the saving of Jewish lives, it would have taken all the allies to negotiate a peace and the emigration of the Jewish population, which ended up being used as hostages in the attempt to keep the US out of the conflict. Once the US entered the war the Final Solution was greatly accelerated, and our failure to at least try to save lives by seeking a peace for at least as long as those lives could be saved, is a bit of a blight. In essence the Allies sacrificed the victims of the holocaust in order to attain their victory. Such is war. And there were other sacrifices of innocents, and the dehumanizing of some of our own population beyond that. So Pacificism, although difficult to defend in practical terms considering the nature of the enemy, still stands on pretty solid moral grounds.
