The Central Council of the Palestine Liberation Organization (PLO) has moved to fully withdraw from the Oslo Accord on Monday, announcing that they are ending their commitment to the deal, and halting all security coordination with Israel.

Halting security cooperation with Israel is a huge move, and it also comes with an announcement that the PLO will withhold recognition of the State of Israel, until such time as Israel agrees to recognize the State of Palestine.

The 1993 Oslo Accord was intended to increase cooperation during a brief transition period leading to Palestinian statehood. With Israel’s far-right leadership having long insisted that the Palestinians will never have an independent state, many in the PLO have argued that security cooperation was just making the permanent Israeli occupation cheaper and giving them legal cover to do things in violation of international law in the occupied territories.

The collapse of the Oslo Accord could greatly increase the cost of the occupation for Israel, because under international law they are obliged to provide certain specific services to the Palestinians, and if the PLO is no longer voluntarily providing them with foreign donated funds, they’ll be on the hook to do it themselves.
