U.S. President Joe Biden met NATO and European leaders in Warsaw on February 22, with the allies vowing in a statement afterward to further "reinforce our deterrence and defense posture across the entire Eastern flank from the Baltic to the Black Sea." Biden, who has now left the Polish capital, attended a meeting with NATO chief Jens Stoltenberg and the heads of Eastern European countries in a bid to shore up support for Kyiv nearly a year after Russia invaded Ukraine. The leaders of Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, and Slovakia joined the talks.
