The response in the room was generally positive, the sources said.Trump told the leaders at the meeting on the sidelines of the UN General Assembly that the war must end urgently, two sources said.Trump noted that he's presenting the plan because every day the war continues, Israel becomes more and more isolated internationally, one source said.Driving the news: The sources said the US. principles presented in the meeting were variations of ideas that have been discussed over the last six months, and updates to ideas developed by Trump's son in law Jared Kushner and former British Prime Minister Tony Blair.The main principles are:The release of all remaining hostages.A permanent ceasefire.Gradual Israeli withdrawal from all of the Gaza Strip.A post-war plan that includes a governing mechanism in Gaza without Hamas.A security force that would also include Palestinians but also soldiers from Arab and Muslim countries.Arab and muslim funding for the new administration in Gaza and for reconstruction of the enclave.Some involvement of the Palestinian Authority.The sources noted that Trump asked the Arab and Muslim leaders for their support of these principles and their commitment to take part in the post-war plan for Gaza.The other side: According to two sources, the Arab leaders presented Trump with several conditions for supporting his plan:Israel will not annex parts of the West Bank or Gaza.Israel will not occupy parts of Gaza.Israel will not build settlements in Gaza.Israel will stop undermining the status quo at the Al-Aqsa Mosque.Humanitarian aid to Gaza will immediately increase.Trump made it clear to the Arab and Muslim leaders that he would not allow Israel to annex parts of the West Bank, two sources said. Politico reported first on Trump's pledge to prevent annexation.At the end of the meeting, the Arab and Muslim leaders expressed support for the American principles and committed to taking part in the post-war plan, the sources said.What they're saying: "The meeting was very good. Trump is definitely committed to ending the war," one Arab official who attended the meeting said. Another Arab official with knowledge of the meeting that the participants left the meeting "very hopeful.""For the first time we felt there was a serious plan on the table. President Trump wants this chapter to be over so that we can move forward to better things in the region," the official said. State of play: On Wednesday, Secretary of State Marco Rubio and Witkoff had a follow up meeting with the foreign ministers of Saudi Arabia, Qatar, the United Arab Emirates, Egypt and Jordan, to turn the principles Trump presented into a more detailed and operational plan.What's next: Israeli officials noted that Israeli Prime Minister Benjamin Netanyahu is generally aware of the U.S. principles and that his confidant Ron Dermer has recently held discussions on the subject with Kushner and Blair.Trump told the Arab leaders that the next step is to discuss the plan with Netanyahu at the White House on Monday in order to secure his support, according to a source familiar with the contents of the meeting."The U.S. outline was good but needed a bit more refining with input from Arab countries. After it is finalized the U.S. will have to sell it to Bibi," an Arab official said. Go deeper: Trump's middle finger to the UN: "Your countries are going to hell"
