Authorizes Member States working with the BoP and the BoP to establish a temporary International Stabilization Force (ISF) in Gaza to deploy under unified command acceptable to the BoP, with forces contributed by participating States, in close consultation and cooperation with the Arab Republic of Egypt and the State of Israel, and to use all necessary measures to carry out its mandate consistent with international law, including international humanitarian law. The ISF shall work with Israel and Egypt, without prejudice to their existing agreements, along with the newly trained and vetted Palestinian police force, to help secure border areas; stabilize the security environment in Gaza by ensuring the process of demilitarizing the Gaza Strip, including the destruction and prevention of rebuilding of the military, terror, and offensive infrastructure, as well as the permanent decommissioning of weapons from non-state armed groups; protect civilians, including humanitarian operations; train and provide support to the vetted Palestinian police forces; coordinate with relevant States to secure humanitarian corridors; and undertake such additional tasks as may be necessary in support of the Comprehensive Plan. As the ISF establishes control and stability, the Israel Defense Forces (IDF) will withdraw from the Gaza Strip based on standards, milestones, and timeframes linked to demilitarization that will be agreed between the IDF, ISF, the guarantors, and the United States, save for a security perimeter presence that will remain until Gaza is properly secure from any resurgent terror threat. The ISF shall, (A) assist the BoP in monitoring the implementation of the ceasefire in Gaza, and enter into such arrangements as may be necessary to achieve the objectives of the Comprehensive Plan; and (B) operate under the strategic guidance of the BoP and will be funded through voluntary contributions from donors and BoP funding vehicles and governments;
