Do you really believe that there is any European country or a group of countries apart from Russia that can actually make a 5th generation aircraft?
Lockheed Martin F-35 doesn't count.
Firstly, 5th generation is a bullshit marketing term dreamt up by LM.
Second the pakfa/T50 is not stealth anymore than the Eurofighter or Rafale. Its RCS its about the same from the front.
What else makes it 5G, I doubt it will have developed. in fact I'm 99% sure that that plane will not be fully operational in the next 20 years.
Russia is a weak, technologically backword country without the people or money to develop anything as advanced as the F22.
Russias economy is as big as Spain, its a not a major power and getting smaller and weaker every day.
