This week, during a media roundtable hosted by the Army, survivors of the Pentagon attack on 9/11 shared their personal experiences.

Particularly compelling is Gerry Kitzhaber, the deputy principal to the assistant secretary of the Army for manpower and reserve affairs for training, readiness and mobilization. At 15:58 on the video clock, he tells how close he came to being in the middle of the inferno when American Airlines Flight 77 hit the Pentagon, and he recounts a conversation with a delivery truck driver who saw the plane hit.

These comments are a stark reminder of two things. First, freedom and liberty come at a high cost. And second, evil is real. Let’s not forget either one.
