Sunday on CNN’s “Fareed Zakaria GPS,” former secretary of defense and the former director of CIA Leon Panetta said “it’s a matter of time” before terrorist attempt an attack on the United States.

Panetta said, “I think what we’re seeing, as I said, is a much more aggressive chapter and a much more dangerous chapter in terms of the war on terrorism. What has happened in Paris, what happened in Ottawa, what has happened in Belgium is something we need to understand that these terrorist are now engaged in a much more aggressive effort based on their recruiting, based on what’s happening in Syria and Iraq and Yemen, they are engaged in a much more aggressive effort to conduct violence not only in Europe, but I think it’s a matter of time before they direct it at the United States as well. This is a real threat and we’ve got to be prepared to confront that.”
