Q & A, Hosted By Jay Nordlinger

Yaroslav Trofimov is the chief foreign-affairs correspondent of the Wall Street Journal. He was that paper’s bureau chief in Afghanistan and Pakistan. His previous books have been about the Middle East and the broader Muslim world. But he was born in Ukraine—and has been covering that war, intensely. His new book is “Our Enemies Will Vanish: The Russian Invasion and Ukraine’s War of Independence.” Jay asks him about essential things.
