Pearl Harbor.

Today in American history on Dec 7, 1941 a Naval Base was struck by the Japanese.  Consider the response at the time...the President met with Congress and Congress declared war.  Our entire nation was mobilized for the effort.  Rationing of strategic supplies...oil, gas, rubber, steel and even food was diverted to support the war effort.  War Bonds were sold so that the nation could fully fund the war...and finally every person over the age of 18 (and many below that age) all found a way to contribute.  I'm not so infatuated with the period to not believe that their weren't slackers...but in general the nation pulled as one.

Remember the attack, marvel at our response and compare it to what would happen today.
