Eight members of Congress have taken a pledge to work to bring ongoing U.S. global military conflicts to a responsible and expedient" end, the result of a first-of-its kind lobbying effort by military veterans on Capitol Hill. The pledge was written and organized by a group called Common Defense ... which advocates for scaling back U.S. military commitments overseas. The effort ... is unique in that it is driven almost exclusively by veterans and focuses on global conflicts broadly, rather than one specific war. In 2001, Congress authorized military operations against the groups responsible for those attacks. In the years since, that congressional authorization has been interpreted broadly and has led to combat against groups, like the Islamic State, that did not exist on 9/11. "The United States has been in a state of continuous, global, open-ended military conflict since 2001. Over 2.5 million troops have fought in this 'Forever War' in over a dozen countries - including Afghanistan, Iraq, Syria, Yemen, Jordan, Niger, Somalia, and Thailand," the pledge reads. It continues: "I pledge to the people of the United States of America, and to our military community in particular, that I will (1) fight to reclaim Congress's constitutional authority to conduct oversight of U.S. foreign policy and independently debate whether to authorize each new use of military force, and (2) act to bring the Forever War to a responsible and expedient conclusion."
