As the world grapples with the scale and severity of the coronavirus pandemic, President Trump has both pointed fingers at and asked for help from the W.H.O., China and international industry. Ambassador Nicholas Burns served as U.S. Undersecretary of State for Political Affairs and U.S. Ambassador to NATO under President George W. Bush.

His essay in Foreign Affairs is “How to Lead in a Time of Pandemic.”
