Research suggests that marginalized groups can use military service to win greater governmental and social acceptance by using civic republican rhetoric, however, conditions in which claims-making rhetoric is coercive are underspecified. Because rhetorical effectiveness requires sympathetic ears, we examine the influence of (1) expectations and political efforts of marginalized group members seeking greater acceptance, (2) whether majority group economic status is outpacing marginalized groups seeking improved treatment, and (3) whether marginalized groups have influential military veterans from majority groups as allies. We apply these factors to explain the claims-making failure of German Jews following the First World War and the success of African Americans after the Second World War. From the African American case, we also conclude that military service led to greater socio-political inclusion and rights based on development of future political actors through leadership development processes and inter-group contact, especially regarding Presidents Truman and Eisenhower.
