The term Greater Israel is subject and means different things to different people.
my meaning is: Greater Israel is Israel, including all of Israel (which includes Gaza and the West Bank, and all land which Israel currently holds, and not lands Israel lays claim to but does not currently hold). To be clear my view is Israel holds both Gaza and the West Bank.
If you disagree with this and dont include either Gaza or the West Bank in the definition of the Term "Greater Israel" then all you have to do is acknowledge them as part of the state of Palestine.
That framing presents a false binary. The fact that these territories are not part of Israel does not automatically make them a functioning State of Palestine. A territory can be neither sovereign Israeli land nor a viable Palestinian state which is, in fact, the current situation.
If Palestinians want statehood, they need to build accountable institutions, unify their leadership, and stop relying on framing everything as Israeli responsibility. Self-determination requires self-discipline not dependency.
