BUCHAREST, Romania (AP) — NATO Secretary-General Jens Stoltenberg says war-torn Ukraine will one day become a member of the world’s largest security alliance. It’s a commitment that NATO leaders made to Ukraine 14 years ago. But some say it led in part to Russia’s invasion. Stoltenberg’s remarks came as U.S. Secretary of State Antony Blinken and his NATO counterparts gathered Tuesday in Romania to drum up urgently needed support for Ukraine, including deliveries of electrical components for the war-torn country’s devastated power transmission network. Ukraine’s grid has been battered since early October by targeted Russian strikes. Stoltenberg says Russian President Vladimir Putin “is trying to use winter as a weapon of war against Ukraine.”
