Seven years ago today, our nation took a major body-blow during the unfathomable terror attacks in New York and Washington D.C. So many innocents were blown away by fireballs of brutality from the evil geniuses of al-Qaeda.

Seven years on, we as Americans have fatigued from the War on Terror. But the reality is that dealing with terrorists is messy and we have a long road ahead of us.

Clark recalls how the British handled the IRA. The IRA would put bombs in metal trashcans to turn them into shrapnel. So the Brits put in plastic trash cans. They also put in cameras everywhere with artificial intelligence to recognize terrorists. The point is they adjusted and they ultimately defeated the IRA. Thus goes our struggle with al-Qaeda.

There are so many ways people have been moved to contribute in the aftermath of 9/11. Clark joined his state guard in November 2001. He didn't have any martial skills at all, so they put him in public affairs. But he's also had opportunities to serve that he never anticipated -- such as when he did medevac relief during Hurricane Katrina.
