Chuck Morse interviews John Koster, author of Operation Snow: How a Soviet Mole in FDR's White House Triggered Pearl Harbor.

In "Operation Snow: How a Soviet Mole in FDR's White House Triggered Pearl Harbor", author and World War II magazine columnist John Koster provides incontestable proof that Russia was a driving force behind Pearl Harbor. Americans have long debated the cause of the December 7, 1941 bombing of Pearl Harbor. Many have argued that the attack was a brilliant Japanese military coup, or a failure of U.S. intelligence agencies, or even a conspiracy of the Roosevelt administration. But despite the attention historians have paid to the bombing of Pearl Harbor, the truth about that fateful day has remained a mystery-until now. In "Operation Snow: How a Soviet Mole in FDR's White House Triggered Pearl Harbor", author John Koster uses recently declassified evidence and never-before-translated documents to tell the real story of the day that FDR memorably declared would live in infamy, forever. "Operation Snow" shows how Joseph Stalin and the KGB used a vast network of double-agents and communist sympathizers - most notably, Harry Dexter White - to lead Japan into war against the United States, demonstrating incontestable Soviet involvement behind the bombing of Pearl Harbor. A thrilling tale of espionage, mystery and war, "Operation Snow" will forever change the way we think about Pearl Harbor and World War II.
