President Trump struck an optimistic tone Monday while touting the U.S.-Iran peace deal, predicting it will transform the Middle East even as daunting questions remain about fighting in Lebanon and the future of Tehran's nuclear program.

Speaking at the Group of Seven meetings in France, Mr. Trump said he signed the memorandum of understanding late Sunday to reopen the Strait of Hormuz and set the table for limiting Iran's nuclear program.
