Call of Duty began with a clear antagonist in the Nazis during its World War II era, but as the series progressed into modern and futuristic settings, the portrayal of enemies became more nuanced. Glen Schofield, a former director of the franchise, noted that the depiction of villains was influenced by themes of jingoism, colonialism, and American interventionism. His perspective was shaped by a personal story from an Iraqi classmate, whose uncle expressed ambivalence about democracy after escaping imprisonment under Saddam Hussein. This narrative inspired Schofield to develop the character of Jonathan Irons in Advanced Warfare, leading to a powerful speech crafted by Eric Hirshberg that reflected this complex worldview. The evolution of Call of Duty illustrates a growing awareness among creators regarding the narratives they present and their potential impact on players' perceptions of global issues.
