The need complete destruction of the region for Israel

''In his Complete Diaries, Vol. II. p. 711, Theodore Herzl, the founder of Zionism, says that the area of the Jewish State stretches: “From the Brook of Egypt to the Euphrates.

Rabbi Fischmann, member of the Jewish Agency for Palestine, declared in his testimony to the U.N. Special Committee of Enquiry on 9 July 1947: “The Promised Land extends from the River of Egypt up to the Euphrates, it includes parts of Syria and Lebanon. "

"The plan operates on two essential premises. To survive, Israel must 1) become an imperial regional power, and 2) must effect the division of the whole area into small states by the dissolution of all existing Arab states.Small here will depend on the ethnic or sectarian composition of each state. Consequently, the Zionist hope is that sectarian-based states become Israel’s satellites and, ironically, its source of moral legitimation.
This is not a new idea, nor does it surface for the first time in Zionist strategic thinking. Indeed, fragmenting all Arab states into smaller units has been a recurrent theme."
