Robert O'Neill, the former Navy SEAL credited with killing Osama bin Laden, the terrorist mastermind behind the 9/11 attacks, said that the biggest threat to America comes not from outside but from internal strife and division.
O'Neill made the remarks in an interview with Fox News on the eve of Sept. 11, as the nation prepared to honor victims of the terror attack on the World Trade Center 20 years ago that killed at least 2,977 people and injured thousands more.
