As the United States marks the 10th anniversary of the longest period of sustained warfare in its history, the overwhelming majority of veterans of the post-9/11 era are proud of their military service. At the same time, many report that they have had difficulties readjusting to civilian life, and have suffered from post-traumatic stress. While veterans are more supportive of the wars in Afghanistan and Iraq than the general public, just one-third say that both been worth fighting. This report is based on two surveys conducted by the Pew Research Center: one of the nation's military veterans and one of the general public. A total of 1,853 veterans were surveyed, including 712 who served in the military after the attacks of September 11, 2001. The general public survey was conducted among 2,003 adult respondents. Three appendices are included: (1) Survey Methodology; (2) Topline Questionnaires; and (3) Supplemental Table on Views on Wars in Afghanistan, Iraq.
