US President Joe Biden has delivered his final address as U.S. president to the U.N. General Assembly. Biden used his wide-ranging address on Tuesday to speak to the need to end the Middle East conflict and highlight U.S. and Western allies’ support for Kyiv after Russia’s invasion of Ukraine. The president insisted the U.S. must not retreat from the world, and said that despite global conflicts, he remains hopeful for the future. His speech comes as Israel and Hezbollah militants in Lebanon edge closer toward all-out war and Israel’s bloody operation against Hamas in Gaza nears the one-year mark.
