Anthropologist and attorney Darryl Li reconceptualizes jihad as armed transnational solidarity under conditions of American empire, revisiting a pivotal moment after the Cold War when ethnic cleansing in the Balkans dominated global headlines. Muslim volunteers came from distant lands to fight in Bosnia-Herzegovina alongside their co-religionists, offering themselves as an alternative to the US-led international community. Li highlights the parallels and overlaps between transnational jihads and other universalisms such as the War on Terror, United Nations peacekeeping, and socialist Non-Alignment. Developed from more than a decade of research with former fighters in a half-dozen countries, The Universal Enemy explores the relationship between jihad and American empire to shed critical light on both.
