Operation Snow: How a Soviet Mole in FDR's White House Triggered Pearl Harbor

Praise for Operation Snow

“I found Operation Snow to be an irresistible page-turner. The attack exacted a terrible toll on both countries and changed the world forever. It is important to understand why that happened. Koster has made a significant contribution.”
— Admiral Ronald J. Hays USN (Ret), former commander in chief Pacific Forces

“To paraphrase Cicero, a nation can survive its fools and even the ambitious, but, as a rule, it cannot survive treason from within, especially when the traitor—in this case Harry Dexter White—is allowed to lead the fools and the ambitious. The U.S. survived. It’s a cautionary tale—the exception that proves the rule.”
— Thomas K. Kimmel Jr., former FBI agent, Pearl Harbor scholar, grandson of Admiral Husband Kimmel

“Fascinating and compulsively readable. What a book! The House Un-American Activities Committee transcripts are arresting in their exposure of White’s duplicity.”
— Louise Barnett, Ph.D., professor of American Studies, Rutgers University, author of Atrocity and American Military Justice in Southeast Asia and Touched by Fire

“John Koster’s Operation Snow opens a whole new window on the Russian role in fomenting Japan’s attack on Pearl Harbor to safeguard Russia’s eastern front.”
— Edward H. Bonekemper III, Civil War historian, author of Grant and Lee

“This book is important because Harry Dexter White was the most dangerous traitor in American history.”
— Mikhail Smirnov, MA, Moscow University, former Soviet soldier
