America faces a “constantly changing” terrorism threat that includes expanding partnerships among al Qaeda-inspired terrorist groups, said Homeland Security Secretary Janet Napolitano.
“More and more, we are seeing a homegrown extremism being an issue,” she said.
“The terrorist threat to our nation is as busy as it has been since anytime prior 911. The difference is that instead of one al Qaeda group, we now have many al Qaeda groups or al Qaeda-inspired groups, including for example AQAP [al Qaeda in the Arabian Peninsula], which has been centered in Yemen, which has been one the busiest ones in terms of attempts on the United States since I have been secretary.”
