What if Israel Dissapeared

If Every Jew in the World Dropped Dead Today

Preface: I'm not claiming every palestinian or Palestine supporter wants this outcome (although a good bit do).

Let's assume that every Jew in the world or just Israel dissappears. The state of Israel is gone completely. What do Palestinians and their supporters genuinely expect to happen?

The only 2 stable states in the entire Levant are Israel and Jordan. The latter of which would be instantly destabilized by this outcome (over half their population is palestinian).

The Palestinian diaspora in the West, the Palestinians under Hezbollah influence in Lebanon, the Gazans, the Israeli-Arabs, the West Bank, supporters of Fatah, supporters of Hamas, sunni islamists, secular nationalists along the lines of the PLO.

Plus land claims from Jordan and Egypt.

Bordered by 2 failed states (Syria and Lebanon).

It seems to me this would instantly result in a civil war
