Together, outcomes such as homelessness and suicide—and other forms of premature death among veterans—may be among the most severe effects of war for America’s veterans. As the wars in Afghanistan and Iraq come to an end and their histories are written, the communications in this issue of Psychiatric Services must be viewed as an early part of the story. As the history unfolds, the wars may leave a legacy of extensive illnesses and injuries. However, there is another possibility. If VA’s programs for homeless veterans and its mental health enhancements prove to be effective, the histories that are written may speak of the war as a catalyst for advances in mental health care for veterans and, by extension, for the nation as a whole. Time and a continued focus on mental health services, program evaluation, and health services research will tell.
