United States of Palestine and Israel (USPI)
This is a federal solution similar to the United States with different regions ruled independently and without real borders/walls, one single currency, airspace, job market, etc. plus international pressure to enforce democracy and not apartheid with military force.

New Palestine (NP)

This is a situation in which Israel disappears and Palestine returns to its pre-1948 borders. In addition this new state will have a duty to protect and enforce a minimum representation for Jewish in the government as well as Hebrew as main language together with Arabic.

Greater Israel (GI)

This is a situation in which Palestine disappears and Israel gets to rule all the land including all of Gaza and the West Bank (in perspective potentially Lebanon, Syria, Iraq and the Sinai desert).

State of The Holy Land (International Commission)

In this case the international community takes over the land and make sure it is safe to access all the holy sites for the main three monotheistic religions. New residents would not be able to elect their representatives, the country will be completely demilitarised and even guns/personal weapons will be banned.
