Sunday marks the fifteenth anniversary of the Sept. 11 terrorist attacks on the United States. Nearly 3,000 people died, including 125 at the Pentagon. As Kellie Lunney writes, the attacks taught Americans "painful but valuable lessons about survival, leadership and community."
The whole of the federal government was involved in the response to the attacks and Congress minted a new agency -- the Department of Homeland Security -- in their wake.
