The former New York City mayor who has sometimes been mocked for using "a noun, a verb and 9/11" in stump speeches appears to have forgotten -- or has mentally reclassified -- the worst terrorist attack on American soil. "We had no domestic attacks under Bush," Rudy Giuliani told ABC's George Stephanopoulos Friday.

Giuliani's remark came amidst a jeremiad against President Barack Obama's handling of the Christmas day Detroit airliner bombing suspect and appears at about 3:21 in the below clip.

"What he should be doing is following the right things that Bush did," Giuliani said. "One of the right things he did was treat this as a war on terror -- we had no domestic attacks under Bush; we had one under Obama."
