Sukhois are great in dogfights. But their avionics are rivaled by your pocket calculator. Have fun hitting anything you can't see in one of those.
American planes are built to be able to dogfight, should missiles fail. Russian planes are made purely to dogfight, because Russians don't trust the missiles. That dogma is as outdated as the one that claimed that missiles will replace dog fighting altogether. So in a close up fight, the Russians might win. But how many will they lose getting to this close up fight?
Chiko?
And when you take into account that the Russian Air Force can barely pay it's bills...
(BVR is now very important as well)
