I'd be interested to hear more about this ... do you have links to a summary ?
> Putin came to power as a result of the US interference, after blackmailing Boris Yeltsin
I'm not clear if you mean Putin blackmailed Yeltsin or the US blackmailed Yeltsin ? What was the blackmail over ?
From a brief bit of reading and what memory I have Yeltsin was having various ...
- health ("months in hospital" [1]),
- political (four prime ministers in eighteen months [2])
- and, allegedly, criminal (government contractor providing Yeltsin and family with "we pay the bills" credit cards [3])
... problems so him going of his own accord doesn't seem impossible ?
Also wasn't it the case that you could only do two terms as President until Putin fixed it so he could reign for ever ? If that was the case then Yeltsin wasn't going to be able to run again anyway ?
I'm open to the idea that the CIA was, as is traditional, shooting itself in the foot, and there may have been US elements who felt that Boris was dangerously unpredictable but it does seem that there was other things going on which might have led to his demise ?
