Unsolved Mysteries of WWII Season 2

The Japanese raid on Pearl Harbor on December 7 1941 shocked the world and drew the United States into the war. Did British Intelligence and Britain's Prime Minister, Winston Churchill, know in advance of the Japanese attack and fail to warn the Americans?

Of the many attempts to kill Hilter the von Stauffenberg attempt came closest to not just killing Hitler but in toppling the Nazi Regime. Although the plot came toward the end of Hitler's reign it had it roots years earlier among the numerous disenchanted members of the Wehrmacht senior staff, the very leaders Hitler needed to carryout his plans for the conquest of Europe. An assassination plot was well underway immediately following Hitler's invasions of Eastern European countries. But a surge in Hitler's popularity and the imposition of the Fuhrer Oath, which German officers considered sacred even though it was imposed on them, lead the conspirators to abandon their scheme, at least for the foreseeable future.

Today, mystery still surrounds Adolf Hitler's fate. What happened to Hitler in the last desperate days of the Third Reich?

What are the origins of this dreaded symbol of the Nazi Party? How did the Swastika change from a Buddhist sign of good fortune to the Nazi emblem which would strike terror into the hearts of millions.

Where did these powerful formations come from? How long had this secret army existed and had Stalin refused to commit them even when Hitler's Armies were at the gates of Moscow?
