Dick Cheney is promoting his soon-to-be-released memoir, In My Time, promising there will be heads exploding all over Washington when people read it.

The vice president under former President George W. Bush will be hitting the airwaves Aug. 29-30 to push the book in interviews on NBC. The promotion has begun with NBC News releasing a portion of a taped Cheney interview.


Among other things, Cheney reveals that he signed a secret letter of resignation shortly after entering office, out of fear for his health.

“I did it because I was concerned that — for a couple of reasons. One was my own health situation,” Cheney said in the interview. “The possibility that I might have a heart attack or a stroke that would be incapacitating. And there is no mechanism for getting rid of a vice president who cant function.”

Cheney also said he has “no regrets” over the use of such “enhanced interrogation techniques” as waterboarding, and that the methods should continue to be employed. Critics have called the practice torture, and in January 2009, President Obama signed an executive order that restricted the use of such techniques.

“I would strongly support using it again if we had a high-value detainee and that was the only way we could get him to talk,” Cheney said.

"This is not an apology tour. It's the book of a proud conservative," a source close to Cheney said, according to the Drudge Report.

Drudge Report also revealed that in the memoir the former vice president criticizes opponents who "peddle falsehoods" about the detention facility at Guantanamo Bay.

The New York Times reported Thursday that the memoir also reveals that Cheney urged Bush to bomb a suspected Syrian nuclear site in 2007.

“I again made the case for U.S. military action against the reactor,” writes Cheney about the episode, adding “but I was a lone voice," according to the Times.

In his memoir, Cheney speculates "the bad intelligence we had received about Iraq’s stockpiles of weapons of mass destruction" contributed to the reluctance to move against Syria.

The former vice president said he and Bush also argued over whether to order an air strike on a target believed to be housing Saddam Hussein. Hussein was later captured in a raid by U.S. forces at a farmhouse near Tikrit.

While Cheney said he doesn’t believe revealing internal White House divisions will strain his relationship with Bush, he “doesn’t know” if the former president will feel betrayed by his memoir.

“I didn’t set out to embarrass the president or not embarrass the president,” Cheney said. “If you look at the book, there are many places in it where I say some very fine things about George Bush. And believe every word of it.”

NBC will be airing the full interview with Cheney on Monday, Aug. 29, on the 10 p.m. episode of “Dateline,” with an accompanying live interview on Tuesday morning’s “Today” show. The memoir also will be released Tuesday, Aug. 30.
