This differential treatment of Palestinian political parties by the Israeli state, including the systematic banning of movements that did not conform to Zionist political boundaries, is one of the ways in which those boundaries were solidified and enforced. The state then demanded that Arab political parties only operate within them, or risk repression. As long as Arab political parties participated in a system that required prior allegiance to an ethnoreligious state that relegated them to the status of second-class citizens, they ended up lending political legitimacy to their own subjugation.
The war on Gaza is fundamentally a war on Palestinian existence everywhere, and it involves a restructuring of borders for each Palestinian faction through methods like forced expulsion, assimilation, or the obliteration of their political identity. The end result is the elimination of the Palestinian people. And in the absence of an alternative political vision that resists the process of Zionist colonial elimination, the Palestinian citizens of Israel will share in the same sordid fate as their Palestinian brothers and sisters.
