Challenge: Establish a Jewish State in Palestine in the twentieth century without the Holocaust

While the 1917 Balfour Declaration favored a "jewish homeland" in Palestine, this was a far cry from a genuine Jewish State, self-sufficient, with a strong military and capacity for self-defense. This was one of the reasons that most jews worldwide were hostile to Zionism. It sounded like Jews going to a voluntary Ghetto, just the opposite of freedom. Aggressive Zionists, of course, were willing to work within this limited framework for a time, realizing that they could, and ultimately did, use terrorist methods to evict the British, and get a Jewish State in Palestine on their own terms. However, most jews worldwide didn't really see much need even for a full-fledged Jewish State, military and all, until Hitler's extermination campaign in the 1940's. What for, exactly? Jews felt reasonably happy, tolerated and comfortable in the U.S. and Europe. Why rock the boat? Who knows, maybe they'd all be deported to this new "Jewish Homeland" in the middle of the desert, surrounded by hostile Arabs. However, once Hitler gave Jews the choice, defend yourselves or die, a powerful State, ever ready to defend them, started looking very attractive indeed! And, it still does. So, is there any way to motivate Jews worldwide to establish a Jewish State in Palestine, without the Holocaust? Thoughts?
