Yes I can maintain whatever I like, thats one thing we can agree on. When did I say tech grows on trees in Russia? You're the one who said Russia doesnt do R+D like they did in Soviet Union, and I rightly pointed out that advanced jets like the Su-35 and 57 didnt just come out of thin air either. Seems you have reading comprehension issues. The Su-35 is definitely a match for the jets you mentioned in your initial comment and only the F-22 and maybe 35 would surpass it. Yes US planes are over priced but that doesnt always trasnlate to value for money. Agree to disagree?
Thats great, but until you show evidence I will have to disagree with you there as well. War is not fought on paper or some video game.
Russia does RnD but 1/500th of the US probably, could be even less.
I am happy to agree to disagree.
