The story's around. But it makes no sense. A surprise attack is a surprise attack whether it sinks seven battleships or is driven off with heavy losses to the attacking air squadrons: the political effect is the same.
It is true that the U.S. military and the White House thought a Japanese attack was not unlikely in December 1941. But if I recall correctly they were much more worried about large-scale sabotage--hence Clark Field in the Philippines, where the B-17s were parked wingtip-to-wingtip so that saboteurs could not get at them, making a perfect target for air attack...
