Ive taken a few years of english, and have been reading since I was 3. I did not understand a damn thing about this analysis. What, exactly, is the objective here? Your psychologist needs to learn language skills first..but of course, the Russians can say anything about their product first. On paper, it may look impressive. In reality, its about a 20% chance -if that- that one of your vaunted Su-30s would even get within range -much less see first- to score a kill against a stealth aircraft. Over the course of 30 years, only 1 stealth aircraft has been shot down. Statistics tell me a whole different story compared to your analysis.
