Why the compulsion to be seen to be right all the time?
Can you at least accept that the only thing you know for a fact is what your sources have told you? You have no way of knowing whether your sources know everything or whether they have simply told you what they want you to hear.
Fwiw, even though I am always suspicious of statements of fact from anybody these days, I think you are probably right, even after all this time, in your assessment of what you have been told. But is there not even a scintilla of thought in your mind that there may be more going on?
Nb: If you reply in a dismissive, obsessive manner, it will only make my question the more relevant :)
