Observe that Robert Gates furtively concealed the fact that it was he himself that was making the prediction
You seem to have misread the article.
Gates didn’t predict the break-up of the Soviet Union. It was a business partner of Stephen Brand who made the prediction in a presentation that Gates saw. According to the article cited by the Wikipedia entry:
At this point, one of the CIA analysts jumped in. The presentation was fine, he said, but there was no way the Soviet Union was going to break up – not in his lifetime, not in his children’s lifetime.
That analyst’s name, said Brand, was Robert M Gates.
Gates was denying that the Soviet Union would break up, not predicting it. Gates “jumped in” on a presentation by someone else. It was that “someone else” who made the prediction.
What evidence supports your claim that Gates ever predicted the break-up of the Soviet Union?
