The Russian invasion of Ukraine is entering its sixth week. Atrocities committed by Russian troops have reached new levels; in Bucha, recent photos show dead, unarmed civilians lining the streets. The harrowing scenes have prompted NATO leaders to consider taking new measures against Russia, namely to equip Ukraine with more weapons and impose more sanctions on Russia. But will those measures be enough? With President Biden now calling the atrocities “war crimes” and Prime Minister Mateusz Morawiecki of Poland “acts of genocide,” what more should NATO do to help protect Ukraine and its sovereignty? On today’s episode of “The Argument,” host Jane Coaston calls upon the former NATO top commander Gen. Philip Breedlove to give context and answers to these large questions. Breedlove is now the distinguished chair of the Frontier Europe Initiative at the Middle East Institute, and he has a lot to say about the alliance’s approach to Russia. “There are people in our government and people in NATO that believe if we keep doing nothing and we just keep doing what we’re doing, supplying them, that the risk will not grow. I’m here to tell you the risk is growing every day,” he says. (A full transcript of the episode will be available midday on the Times website.)
