While it's current leadership is being extremely blatant in it's actions, it's far from an aberration in terms of the country's history. The country's modern founder, Ben-Gurion, stated that Israel should be expanded to it's 'biblical borders'.
Just a small sample:
“We must do everything to insure they (the Palestinians) never do return.”
David Ben-Gurion, in his diary, 18 July 1948, quoted in Michael Bar Zohar’s Ben-Gurion: the Armed Prophet, Prentice-Hall, 1967, p. 157.
Ben Gurion also warned in 1948: Assuring his fellow Zionists that Palestinians will never come back to their homes: “The old will die and the young will forget.”
“We should prepare to go over to the offensive. Our aim is to smash Lebanon, Trans-Jordan, and Syria. The weak point is Lebanon, for the Moslem regime is artificial and easy for us to undermine. We shall establish a Christian state there, and then we will smash the Arab Legion, eliminate Trans-Jordan; Syria will fall to us. We then bomb and move on and take Port Said, Alexandria and Sinai.”
David Ben-Gurion May 1948, to the General Staff. From Ben-Gurion, a Biography, by Michael Ben-Zohar, Delacorte, New York 1978."
