On Monday, Vitaly Churkin, Russia’s permanent representative to the United Nations for the last decade and one of the world’s most effective diplomats, passed away. I was America’s permanent representative to the United Nations from 2013 until President Trump took office, and over the last few years I was probably Ambassador Churkin’s most visible foe. He faithfully defended President Vladimir V. Putin’s deadly actions in Ukraine and Syria. At the same time, Vitaly was a masterful storyteller with an epic sense of humor, a good friend and one of the best hopes the United States and Russia had of working together. I am heartbroken by his death.
