President Obama addressed the United Nations General Assembly this morning, his final speech before the international governing body.

As he nears the end of his two terms in office, the president spoke about some of his administration’s biggest foreign policy initiatives, including the importance of the Paris climate accord, the nuclear deal with Iran and fighting the Ebola epidemic in West Africa.

He also talked about the ongoing, multisided war in Syria. His speech comes the day after a cease-fire brokered by the United States and Russia collapsed, in part because of distrust sowed by an accidental strike by a U.S-led coalition aircraft that killed Syrian soldiers over the weekend. And on Monday, an aid convoy in Syria was attacked from the air.
