ok, go wild. What aircraft? Make sure they were in service during the first 6 months of 1937.
I think it'd be ME109B vs HAwker Fury and Gloster Gladiators in Britain, I16s and I15s in the East, while an attack against Pearl Harbor would be carried out with A5M Claudes and 'opposed' by Seversky P35 fighters and P26 Peashooters. Not much of a contest here.
