From CBS News:
…[A]fter 2 1/2 years of reviewing pre-war intelligence behind closed doors, the lead Democrat on the Intelligence Committee, Sen. John Rockefeller of West Virginia, who voted for the Iraq War, says the Bush administration pulled the wool over everyone’s eyes.
"The absolute cynical manipulation, deliberately cynical manipulation, to shape American public opinion and 69 percent of the people, at that time, it worked, they said ‘we want to go to war,’" Rockefeller told CBS News correspondent Sharyl Attkisson. "Including me. The difference is after I began to learn about some of that intelligence I went down to the Senate floor and I said ‘my vote was wrong.’"
Rockefeller went a step further. He says the world would be better off today if the United States had never invaded Iraq - even if it means Saddam Hussein would still be running Iraq.
He said he sees that as a better scenario, and a safer scenario, "because it is called the ‘war on terror.’"
"…[Saddam] wasn’t going to attack us. He would’ve been isolated there," Rockefeller said. "He would have been in control of that country but we wouldn’t have depleted our resources preventing us from prosecuting a war on terror which is what this is all about."
