Then, Christiane asks her exclusive guest, the Army Vice Chief of Staff, General Peter Chiarelli, how this can be happening in America? Christiane will explore with General Chiarelli the stresses and strains on our fighting men and women and the long-term consequences of their repeated deployments as they transition back to the civilian world.
