The linchpin of any lasting peace will be the creation and deployment of an international force, a feature of the U.S. peace plan that was announced by President Trump and endorsed by world leaders in Egypt earlier this month and that spawned the cease-fire. The force would create conditions to realize other aspects of the plan: filling the growing security vacuum in Gaza, allowing for Palestinian self-governance and ensuring that Israel will not be threatened. At a later stage, once the force is in place and can stabilize Gaza, the thornier political questions in the peace plan, such as how to disarm Hamas, can be addressed.
