Joe Biden is set to deliver his final address as U.S. president to the U.N. General Assembly. Biden's speech on Tuesday comes as he struggles to use his influence to stem a conflict in the Middle East that has put Israel on the precipice of all-out war with Hezbollah militants in Lebanon.

This is one of Biden’s final opportunities to tout his foreign policy legacy on the world stage, but the focus is likely to be on an escalating conflict.

Amid the risk of a wider war, Biden is beginning to acknowledge he is running out of time to help forge a cease-fire and hostage deal with Hamas, aides say.

President Biden is expected to make one of his final major speeches on the world stage when he gathers with leaders from across the globe in New York for the United Nations General Assembly. Among the expected topics for the heads of state are the wars in Gaza and Ukraine.
