The U.S. military is currently engaged in its largest and longest operations since the Vietnam War. The deployments associated with those operations have raised concerns about the armed forces' ability to recruit and retain the personnel they need to carry out those missions. Some observers have also voiced concern that not all segments of U.S. society are fully participating in the fighting. To increase the size of the military and to ensure that it broadly represents the populace, some people have suggested reinstating a military draft.
