Have a different WWI. The Jews has been allowed to buy land in the Jerusalem region since the end of WW1, by the British. Give the Ottomans a marginally better showing and have them retain control of the Lebanon, Syria and Palestine regions. The Jewish population would not be able to establish it'self as well as OTL if this were to happen.
Now what you need a nation in Europe to be Anti-Fascist. You can't use Russia, because the Communists were almost as Anti-Judaism is the Nazis. Post war Germany would be interesting, but I almost feel as if one of the Lowlands offering reading the writing on the wall and offering sanctuary to the Jews would be the best place to start. (Hitler will attack, it is only a matter of time, might as well antagonize the ****). Then post war the Jews are offered a stretch of land acting a buffer nation for the Dutch and establishing a true Jewish State.
That said, it doesn't feel very realistic. Jerusalem was the Homeland of the Jews. They all share a cultural bond due to this. Even if the allies did set this nation up in Germany, they probably wouldn't be as successful as OTL.
