Yeah, the giant japanese fleet was just cruising innocently around the pacific, when one of their subs, which had wandered off to do a little sightseeing of military targets, was visciously attacked by the americans who happened to live there. The japanese, who had been planing to turn around and go peacefully home after their siesta, were instead enraged by the unprovoked attack and swiftly retaliated.
I'm sure there's a _lot_ of historical evidence backing up that view.
Hey, i think we can apply this tactic to the modern day! Let's send the entire US Army and Airforce on an all expense paid vacation to the area just outside of Baghdad. Perfectly innocently of course, but if anyone shoots at them or anything we can respond to the unprovoked attack by leveling the city.
