The new cease-fire also gives an oversight role to the United States, which Iran and Hezbollah have long railed against for its staunch support for Israel. Iran and Hezbollah would have only accepted such an arrangement if they were desperate to stop the war, analysts said.

The ceasefire agreement between Israel and Hezbollah is a major diplomatic breakthrough that follows 13 months of escalating conflict, upheaval and displacement in Lebanon.

The Biden administration kept President-elect Donald Trump’s administration closely apprised of its efforts to broker the ceasefire deal between Israel and Hezbollah that took effect early Wednesday.
