Health,
This idea that since some early Zionists in the process of making a state thought it was a good idea to slowly ease into the region and not just declare a state outright to the Pretty hostile English and the very hostile Arabs has no bearing on what would have happened had there been a state of Israel earlier.
The fact remains that Israel is the only country that allows Jews to settle in its borders and grants them citizenship simply by virtue of them being Jews.
If there was a state during WW2, there would of course have been no immigration quotas in the state, just like every religious, not religious and even anti Zionist Jew is given the right to settle is Israel now with no questions asked-just because they are Jewish.
