Those airforces don´t have the ability to maintain their aircraft properly and they barely can afford flying hours for training. Also, Russia exports downgraded Mig-29 only. A difference could be the Mig-28sy. The most countries can´t maintain the engines. Cuban Mig-21 engines go to North Korea for the overhaul.Consistent with the number of facts in your other posts. Zero.Shut the fuck up, liar.
Tell us more abut the invincible MIG-29 that has consistently been on the losing end of any air combat against modern fighter jets? Dumbass. You're like the National Enquirer of defense tech, lots of made up stories and backtracking when busted talking out of your ass.
