From a January 8 PolitiFact.com post:

Giuliani, the former mayor of New York City and a candidate for president in 2008, appeared on Good Morning America on Jan. 8, 2010, to offer his assessment of the Obama administration's counterterrorist operations. He criticized plans to try suspected Christmas Day bomber Umar Farouk Abdulmutallab in a Michigan criminal court and questioned Obama's decision to close the prison at Guantanamo Bay. Giuliani said U.S. intelligence agencies stand to lose potentially critical information on other al-Qaida operatives and operations if the man at the center of the Northwest flight terror incident is tried in U.S. court. “What he (Obama) should be doing is following the right things that Bush did -- one of the right things he did was treat this as a war on terror. We had no domestic attacks under Bush. We've had one under Obama,” Giuliani said. “Number two, he should correct the things that Bush didn't do right. Sending people to Yemen was wrong, not getting this whole intelligence thing corrected was both Bush's responsibility and Obama's.”

Giuliani, the mayor of New York City during the Sept. 11, 2001, terrorist attacks, claims there were no domestic attacks under the Bush administration. That's obviously a preposterous statement that would warrant a Pants on Fire rating. We can't help but remember now-Vice President Joe Biden's line during his presidential campaign, “Rudy Giuliani -- there's only three things he mentions in a sentence. A noun and a verb and 9/11.”

Unfortunately, interviewer George Stephanopoulos never sought clarification on Giuliani's statement. After the interview, Stephanopoulos updated his blog to say Giuliani was wrong to say there were no domestic attacks under Bush.

Media Matters For America, a liberal group that analyzes the news media, documented other examples of U.S. terrorism:

2002 attack against El Al ticket counter at LAX. Hesham Mohamed Hadayet opened fire at an El Al Airlines ticket counter at Los Angeles International Airport, killing two people and wounding four others before being shot dead. Media Matters found a 2004 Justice Department report that Hadayet's case had been “officially designated as an act of international terrorism.”

Campus attack at UNC. In March 2006, a University of North Carolina at Chapel Hill graduate drove an SUV onto campus, striking nine pedestrians. Reza Taheri-azar reportedly stated in a letter: “I was aiming to follow in the footsteps of one of my role models, Mohammad Atta, one of the 9/11/01 hijackers, who obtained a doctorate degree.”
