As the Russian invasion of Ukraine enters a third month, prospects of ending the conflict are still nowhere in sight, and there seems to be no end to the destruction that Vladimir Putin is willing to inflict. Sergiy Kyslytsya, Ukraine’s Permanent Representative to the United Nations, tells David Remnick that he expects Russia to continue escalating its attack leading up to May 9th, a day of military celebration in Russia commemorating the German surrender in the Second World War. “They will escalate attacks by missiles from the sky to terrorize Ukraine in general,” he predicts, “and to make the government more susceptible to surrender.” In contrast to President Volodymyr Zelensky—who was a political rookie when he took office, in 2019—Kyslytsya has spent his career in Ukraine’s foreign service. In the years after the Soviet breakup, he says, Ukraine wanted to both placate its neighbor and ally itself with Western institutions. This created a “cognitive dissonance,” he says, that prevented Ukraine from recognizing the extent of Russian aggression. Having watched as diplomacy failed, Kyslytsya still has to separate his work from the personal toll of Russia’s invasion on his family and friends. “I try not to engage emotionally because if I engage emotionally too much, I am not operational,” he says. “And if I am not operational . . . I’m of very little use for my government.”
