"The land of Israel is not small at all, if only the Arabs will be removed, and if its frontiers would be enlarged a little; to the north all the way to Litani, and to the east including the Golan Heights. ... while the Arabs be transferred to northern Syria and Iraq. ... From now on we must work out a secret plan based on the removal of the Arabs from here ... to include it into American political circles. ... today we have no other alternative... We will not live here with Arabs"
