NATO’s renewed strength and commitment to its original mission of countering an aggressive Russia in Europe was on full display at the alliance's 75th-anniversary summit in Washington, DC. On GZERO World, Ian Bremmer sat down with Poland Foreign Minister Radek Sikorski on the sidelines of the summit to discuss the mood among NATO allies and Sikorski’s assessment of the battlefield two and a half years into a bloody, brutal war with no end in sight. Sikorski, whose country shares a 300+ mile border with Ukraine, remains optimistic that Russian defeat is inevitable.

“Putin misjudged us. He thought Ukraine would just cave in and he’d walk into a victory parade,” Sikorski says, “I don’t think in his worst dreams he anticipated we’d be spending hundreds of billions on arms and ammunition and that two years on, he’d still be controlling only 20% of Ukrainian territory.”
