I like Rocco's restitution idea. There is a precedent for restitution of the colonizer to the colonized right here in America.
Restitution to the Palestinians for the land stolen from them, their eviction and the various massacres, injustices suffered at the hands of the Zionists could parallel those that have been paid (and are actively being pursued in court) by descendants of the affected Native Americans vis-a-vis the U.S. Government.
The Native Americans have been bringing the U.S. to court in a number of individual legal actions including Homer Flute et al. v. U.S. et al., case number
14-1405, in the U.S. Court of Appeals for the Tenth Circuit, where reparations are being claimed for reprisals by the U.S. Army for Indian attacks on white settlers, in which the U.S. Army killed Native American civilians (women and children) in reprisal attacks. While the U.S. Cavalry attack on the Indian encampment that the "braves" returned to occurred in 1864, there is no statute of limitations because of the nature of the crime. And, the Government admits the U.S. Army ignored clear indications that the encampment housed civilians in addition to the "braves" that had attacked the white settlers.
Whether the U.N., Great Britain, the U.S. (as the facilitator of the Israeli attacks on civilians) or Israel should pay the reparations is the question.
