Herzl wanted to drive out most of the people of any land that would become Israel. Jabotinsky and Ben-Gurion had the same goal--they only disagreed on how to do it.

Similarly, the Nazis did not implement the Final Solution until 1942. If the world had helped Hitler ethnically cleanse the countries he conquered, the Nazis would have been content. Look at the friendliness between Nazis and Zionists in the '30s, probably another subject I should write about.
