Tenet also says his famous "slam dunk" remark about the evidence that Iraq had weapons of mass destruction was taken out of context.
Tenet says he used the term to refer broadly to the public case that could be made against Hussein, not his alleged weapons of mass destruction (WMD).
When no WMD was found, Tenet says he was publicly blamed by the administration for exaggerating the evidence.
'Trust Was Broken'
Tenet spoke bitterly about the incident in the U.S. television news program "60 Minutes."
"You are going to throw somebody overboard just because it's a deflection? Is that honorable? It's not honorable to me," he said.
"Now, how it happened and who orchestrated it and what happened -- you know, at the end of the day, the only thing you have is trust and honor in this world," he added. "All you have is your reputation built on trust and your personal honor, and when you don't have that any more, well, you know, there you go. Trust was broken."
In the book, Tenet takes blame for the flawed 2002 "National Intelligence Estimate" about Iraq's weapons programs.
"At the Center of the Storm" will be published on April 30.
