For a country that represents itself as Judaism itself, they sure do have an obsession with making the rest of the Middle East disappear
Torah - Genesis Chapter 15 verse 18-21
18 - On that day, the Lord formed a covenant with Abram, saying, "To your seed I have given this land, from the river of Egypt until the great river, the Euphrates river.
19 - The Kenites, the Kenizzites, and the Kadmonites,
20 - And the Hittites and the Perizzites and the Rephaim,
21 - And the Amorites and the Canaanites and the Girgashites and the Jebusites.
So modern day Zionists believe the Jewish people have a divine right to the lands in the middle east, they refer to these lands as "greater israel" and includes
Israel and Palestine, Lebanon, Jordan, Syria, Iraq, Parts of Egypt (up to the Nile), Parts of Saudi Arabia, Parts of Turkey
This doctrine is also important to American Evangelicals (also zionists) as they believe israel needs to claim these lands + sacrifice the red heifer which will cause Armageddon, god will kill all the Jews and christians will be raptured to heaven.
EDIT: It needs to be said, not every practicing jew of any tribe is a zionist
