WASHINGTON (CNN) -- Donald Trump has two words for the Bush Administration: "You're fired."

The business mogul didn't hold back in criticizing the administration in an interview with CNN's Wolf Blitzer Friday, calling President Bush, "probably the worst president in the history of the United States." (Read full interview transcript [PDF])

He labeled former Secretary of Defense Donald Rumsfeld a "disaster," and accused Secretary of State Condoleezza Rice of "never making a deal." He also charged Vice President Dick Cheney of sugarcoating the conditions in Iraq.

"I don't know if they're bad people. I don't know what's going on. I just know they got us into a mess, the likes of which this country has probably never seen," Trump said. "It's one of the great catastrophes of all time." (Watch Video: Trump sounds off on politics)

He also said the best course of action in Iraq is to "declare victory and leave."

"Because, I'll tell you, this country is just going to get further bogged down," Trump said. "They're in a civil war over there. There's nothing that we're going to be able to do with a civil war."

Asked whether Trump was considering making a bid to succeed President Bush, he said he was "not interested in running," though admitted, "It would certainly be fun. It would certainly be interesting."

Trump also sized up some of the current presidential candidates, calling Sen. Hillary Clinton "very talented, very smart," Sen. Barack Obama a "star," former New York City Mayor Rudy Giuliani "very formidable in every way," and former Massachusetts Gov. Mitt Romney a "very attractive guy." He also said he "respects" Arizona Sen. John McCain.
