This is the U.S. Government's official story of the Zimmermann  Telegram. This book, classified CONFIDENTIAL even 45 years after World War I, is  now unclassified -- and available to historians and scholars. The secret  "breaking" of the German diplomatic code by British cryptanalysts caused a  momentous bombshell which exploded in the American press on the morning of March  1, 1917. Result: the U.S. entered into WW I.
