Just like how your Russian idols speak only irrefutable truth?
Popular perception is irrelevant. Just because most people believe something does not make that something real.
However, unless someone can provide evidence that what they said is fact, then any conclusions they derive are just opinions. For example, if the designers of the J20 went on record saying it was designed as a strike plane, then thats
fact. However, some 'genius' arguing that the J20 is a strike plane because 'tis long', is about as far from a fact as you can get.
Reputation and credibility is critical in determining whether someone's opinion is worth listening to. Its not perception, but basic common sense.
That's just circular reasoning. But its not even a very good one, as what you are saying is that what those Russian analysts said is completely irrelevant. If that's what you meant to say, than I agree. However, I get the feeling you were trying to make a somewhat different point, but got confounded by your own 'upmost logic'.
