Day of deceit - Robert B Stinnett

This book will shock. It shows that Pearl Harbor was not an accident - a mere failure of American intelligence, nor a brilliant Japanese military coup - but the result of a carefully orchestrated design, initiated at the highest levels of the US government. Leading officials felt that the unprovoked strike was the only way a reluctant American public could be galvanised into action, to enter and end what had become a world war.
What did America know, and when? These questions have never been properly answered. Until now. Stinnett offers cable after cable of encryptions, proof of a Japanese spy on the island who transmitted information including a map of bombing targets, and reveals that Admiral Kimmel was prevented at the eleventh hour from conducting a routine training exercise that would have detected the oncoming Japanese fleet. The evidence is overwhelming. Day of Deceit is the definitive final chapter on America's greatest secret and their worst military disaster.
