The Telegraph is MI6's house journal, so evidently some spooks have got the hump and planted a story. Been going on years (remember the anti-Galloway smears that cost them a fortune? Same source). MI5 use the Sunday Times, of course.
The Telegraph is less the Telavivegraph than it was under Conrad Black and his neocon chums, but nevertheless comes from that sector of the map (pro-Likud and very Israel-friendly. Given that, I don't believe the story, too loose and too unattributed.
What's actually happened in the CIA is an internal coup against the previous management who'd spin and suppress intelligence to please Bush and Cheney, leading to the Iraq debacle. After that, professional intelligence veterans got their voice back. It's rather illogical to say that because they were too hawkish over Iraq they're too soft over Iran, since it implies that no matter how bad the cockup they're incapable of fixing it. The history of US intelligence failures - Pearl Harbor and Vietnam* - show that they're very good at sorting things out *after* the horse has bolted. It all comes down to who you believe, professional intelligence gatherers who are trying to put their organisation back together, or the people who broke it.
Meanwhile, in the real world:
