United States Homeland Security Secretary Janet Napolitano has instituted an "all hazards" approach to public safety since joining the Obama Administration.
Homeland Security grew from the ashes of September 11, 2001 in response to the terrorist attacks on New York and Washington. Yet, Homeland Security Secretary Janet Napolitano won't single out terrorism as the biggest threat to the security of the nation.
"There are always a number of threats to our security," Napolitano said during a news conference at the State Emergency Management Agency in Jefferson City. "They can be international, they can be terrorist, they can be domestic and domestically raised. So, it's hard to say what is the single largest."
