HUH yeh a bit of Sarcastic humour 
remember Russia was always a shade behind in aircraft but America did give them the Specification's to the P-51 so that they could also build a better fighter.
Not really, no. Russia's designers were just as capable as anybody other nation's. They had to factor in a few things that American, British and German designers didn't. 1) They had less power to work with, so keeping an aircraft as light as possible was paramount. The Japanese had that problem too, but were further hampered by the need to fly long distances. 2) Keep use of strategic materials to a minimum, which couples nicely with point 1. 3) A less advanced manufacturing base required greater simplicity in construction. 4) The need to operate in comparatively crude conditions was a required design consideration. They did not have to worry overmuch about making their aircraft extremely long ranged to penetrate deep into enemy territory.
