If Israel becomes "gone," I don't think Iraq is going to allow the hundreds of thousands of descendants of the Iraqi Jewish community that was driven out between 1948-1953 to return. There is now a widespread (though also not universal) rejection of Jews being allowed to remain in Muslim countries.

Agreed. But prior to the creation of Israel, would they have been? Why were the villages destroyed? The annexation of land to create "Israel" p-o'd a lot of people in the region. It is my understanding (possibly in error?) that at least part of that animosity was "we don't want the Palestinians in our territory", but displacing them to create Israel meant they had to go somewhere. Was that why they were destroyed?

There's too much animosity built-up to expect that any nation in the region would accept the Jews/Israelis should we suddenly dissolve the nation of Israel. I expect the US would take some, probably a lot of Europe...Russia? Russia used to have lots of Jewish persons (not that they should go to Russia right now...Putin would use them as cannon fodder).

I'll check out your link shortly. Seems there's a wiki entry for almost every question!
