Thanks for that angle. The desire to repeat ones brightest hour can certainly be a strong force and might lead even the most careful astray when a big scoop like Abu Graib makes all further successes seem trivial. I'm not suggesting that he personally made it up, but his desire to believe could be spectacularly strong, turning him into an instrument that is easy to play by people with an agenda.
But I'm biased as well, my desire to believe is strong, only that I'm in team "'t was an inside job" so my bias is in clear opposition of these claims (but in limited to speculation, I find "Russia jumped from excuse to excuse to keep the pipelines closed anyways, so the only immediate winners of the explosions were people in Moscow who felt threatened by some real or imagined "make money not war" faction" logically compelling, but that's all there is, I guess, strongly, but can't claim to know)
