Zionist leaders stressed the strategic advantages to Britain of a "Jewish     state" in Palestine. In a letter written in 1914 to a sympathizer, Chaim Weizmann said:
"... should Palestine fall within the British sphere of influence,  and should Britain encourage a Jewish settlement there, as a British  dependency, we could have in 20 to 30 years a million Jews out there -  perhaps more; they would ... form a very effective guard for the Suez  Canal."  (UN: The Origins And Evolution Of Palestine Problem, section II)
Another  Weizmann letter of 1916 reads:
"... The British Cabinet is not only sympathetic toward the  Palestinian aspirations of the Jews, but would like to see these  aspirations realized ...
England ... would have in the Jews the best possible friends, who would  be the best national interpreters of ideas in the eastern countries and  would serve as a bridge between the two civilizations.  That again is  not a material argument, but certainly it ought to carry great weight  with any politician who likes to look 50 years ahead."
