Russian President Vladimir Putin acknowledged that his “special military operation” in Ukraine is taking longer than expected but said it has succeeded in seizing new territory and added that his country’s nuclear weapons are deterring escalation of the conflict. “Of course, it could be a lengthy process,” Putin said of the more than 9-month-old war that began with Russia’s invasion Feb. 24 and has displaced millions from their homes and killed and wounded tens of thousands. Despite its length, he showed no signs of letting up, vowing to “consistently fight for our interests” and to “protect ourselves using all means available.” He reiterated his claim that he had no choice but to send in troops, saying that for years, the West responded to Russia’s security demands with “only spit in the face.”
