Where should Israel go back to then?

Israel doesn’t have to go anywhere. No more than South Africa went somewhere after Apartheid ended in that state. Or Cuba vanished after the Batista government collapsed. Or Germany vanished after '45.

But the war criminals leading the current genocidal policy towards the people in their care. They need the same treatment as Milosoviec, Omar al-Bashir, and Saddam Hussein.

Drag Netanyahu to the Hague and prosecute him for crimes against humanity. Dismiss the current illegal and unconstitutional Kinesset and hold new free and fair elections in Israel. Provide reparations for the displaced Gaza and West Bank citizens, and launch a Truth and Reconciliation Committee to recover damages for the crimes committed against them.

That is the only moral path forward for Israel.
