Why would you say that the Nazi's were cursed and the Jews blessed? If you look at how many people died, more Jewish civilians were murdered than German soldiers and civilians combined. Certainly that doesn't seem like a very effective curse, does it?
1. God didn't curse the Jewish civilians. The Germans did and because of it were cursed of God and totally devastated.
2. God warned the Jews that because of their idolatry and disregard to his laws, etc, they would be scattered and persecuted by foreign nations a long time ago. These nations, however would not go unpunished, though they were fulfilling prophecy. Jesus and the OT prophets prophesied this, but promised that in the end times he would restore them from the nations and restore their land and nation. Actually the holocaust in Europe worked to drive them back to their land so as to becoming a big factor in fulfillment of the prophecy. God promised via both OT and NT prophets, a ruling messiah to eventually come and rule the world from Jerusalem. This is the essence of Zionism. So in that sense I am a Christian Zionist in that I believe Jesus the christ will return to fulfill his promise in his Olivet discourse and elsewhere.
I'm definitely not trying to imply that the Nazis had God on *their* side or anything, but just because they lost the war to a numerically overwhelming force doesn't mean they did poorly. I'd be more careful about saying that God favours a certain side over another, because you'll see that the numbers doesn't always agree with you.
The war was not lop sided. The West was totally caught off guard when Japan entered. The war was nip and tuck with some doubt as to who would emerge victorious. Germany was developing some sophisticated weapons and along with Italy and occupied nations had the head start before the West got organized. Regardless of the
numbers, the enemies of the Jew were devastated with severe punishment in the end. So it went with the Arab wars, all of which the Jews were highly outnumbered (about 20 to 1) and in the early wars highly both outnumbered and out weaponed, Russia siding with the Arab nations.
According to the prophecies concerning Armageddon which will be in the Valley of Jehosaphat, i.e. the Kedron valley outside Jerusalem, a 200,000,000 million army moving in from the East will be involved, likely, imo, contending with the Russo-Arab alliance for the big prize, world domination. Russia and northern Europe will be the primary invaders again allying with the Arab nations. Read about it in Ezekiel 38, 39. There will be so many dead invaders that Israel will take 7 months to bury them.
