Tronsky,
I'm afraid you're wrong about the P-38 my friend. It did shoot down more Japanese aircraft than any other U.S. Army Air Force fighter.
Credited with some 5,200 victories, carrier- and land-based F6Fs destroyed as many Japanese aircraft as the P-38, P-40, P-47, P-51 and P-61 combined, including those in the landlocked China/Burma/India theater.
