It’s one of Margaret Thatcher’s most memorable quotes, spoken to President George H.W. Bush after Iraq’s 1990 invasion of Kuwait: "Remember, George, this is no time to go wobbly."

It evokes the image of a weak-spined Bush, bolstered by the Iron Lady.

Dick Cheney, the defense secretary who would become vice president, recently called it "an old wives’ story."

And we said: Really?

Cheney fondly recalled the former British prime minister, who died Monday, in an interview that day with Fox News anchor Greta Van Susteren.

Van Susteren: "But there's that famous quote where, apparently, she told President Bush 41 not to go wobbly."

Cheney: "That's not true."

Van Susteren: "That's not true?"

Cheney: "Not true, no."

Van Susteren: "That's a falsehood."

Cheney: "An old wives' story. There was never any doubt about what the president was doing. He didn't need any bucking up."

The same day, the Christian Science Monitor published: "Margaret Thatcher: 'This is no time to go wobbly' and other memorable quotes." The New York Times mentioned the line in her obituary.

Is the quote just "an old wives’ story"?
