 This is The World. I'm Marco Werman. And I'm Carolyn Beeler. Thank you for being with us on this Wednesday. Washington is playing host to its closest allies this week as world leaders converge for a NATO summit. Last night, President Biden addressed many of them, affirming the alliance's strength in the face of Russian aggression in Ukraine. Before this war, Putin thought NATO would break. Today, NATO is stronger than it's ever been in its history.
