Nationalist superheroes—such as Captain America, Captain Canuck, and Union Jack—often signify the “nation-state” for readers, but how do these characters and comic books address issues of multiculturalism and geopolitical order? In his engaging book Captain America and the Nationalist Superhero, geographer Jason Dittmer traces the evolution of the comic book genre as it adapted to new national audiences. He argues that these iconic superheroes contribute to our contemporary understandings of national identity, the righteous use of power, and the role of the United States, Canada, and Britain in the world.

Tracing the nationalist superhero genre from its World War II origins to contemporary manifestations throughout the world, Captain America and the Nationalist Superhero analyzes nearly one thousand comic books and audience responses to those books. Dittmer also interviews key comic book writers from Stan Lee and J. M. DeMatteis to Steve Englehart and Paul Cornell.

At a time when popular culture is saturated with superheroes and their exploits, Captain America and the Nationalist Superhero highlights the unique relationship between popular culture and international relations.

In Diplomatic Material Jason Dittmer offers a counterintuitive reading of foreign policy by tracing the ways that complex interactions between people and things shape the decisions and actions of diplomats and policymakers. Bringing new materialism to bear on international relations, Dittmer focuses not on what the state does in the world but on how the world operates within the state through the circulation of humans and nonhuman objects. From examining how paper storage needs impacted the design of the British Foreign Office Building to discussing the 1953 NATO decision to adopt the .30 caliber bullet as the standard rifle ammunition, Dittmer highlights the contingency of human agency within international relations. In Dittmer's model, which eschews stasis, structural forces, and historical trends in favor of dynamism and becoming, the international community is less a coming-together of states than it is a convergence of media, things, people, and practices. In this way, Dittmer locates power in the unfolding of processes on the micro level, thereby reconceptualizing our understandings of diplomacy and international relations.
