Biden aimed to prove US and global doubters wrong with NATO speech

With the eyes of the world on him, President Joe Biden delivered a forceful speech to open the NATO summit in Washington, aiming to reverse doubts about his fitness for the job domestically while boasting that his leadership revitalized the storied alliance and saved Ukraine. The address, which kicked off three days of high-profile meetings in the steamy U.S. capital, served as both a political and geopolitical test for Biden.
