To mobilize support for war and to control dissent, governments draw upon deeply engrained discourses regarding soldiering and the citizen's duty to support the troops. We identify the cultural and political evolution of the discursive legacy of "support the troops" from the Vietnam War through the Iraq War. Using longitudinal and comparative organizational analyses, we analyze how this discursive legacy was engaged by U.S. peace movement organizations (PMOs).

PMOs frequently made positive references to U.S. troops during both the Gulf War and Iraq War, creating a stable discourse centered around supporting the troops. Moreover, during the Gulf War the movement expanded the web of support by asking who else should be cared about beyond the troops, thus de-coupling the support discourse from the nation and the state. During the Iraq War, PMOs also developed an elaborated "discourse of betrayal" by redefining what it means to support the troops. Here they deployed proactive, anticipatory discourses, turning the tables on the Bush administration. PMOs also increasingly criticized the troops during the Iraq War due to well publicized human rights abuses.

The findings demonstrate that movement discourses are both stable and flexible, influenced by past rounds of discursive contention as well as contemporary political events. We highlight the cultural constraints imposed on movements by dominant discursive legacies, and the strategic responses made by movements in response to emerging discursive opportunities.
