I'm a history buff, and I've read the definitive works on Pearl Harbor and the immediate aftermath by Gordon W. Prange. That's why the story of the discovery of the Japanese midget sub that was sighted and fired-upon by the USS Ward hours before the aerial attack commenced. While it's an interesting bit of history, the (London) Guardian's headline though shows that it's always America's fault.

Submarine could prove US started Pearl Harbor

Yep. We were asking for it.
