Assessing asymmetric wars in the abstract is a problematic task, even though most are “small wars” fought by “big nations.” Armed conflicts with these characteristics brim with persistent, undeclared, and low-intensity violence. It rarely is extinguished, and the lingering injuries sustain even more violence on the same scale. Many of these small wars began in Asia, Africa, Latin America, or the Middle East during, or not long after, World War II. Armed resistance there never completely ended; instead it intensified with decolonization and/or postcolonial state failure. Now virtually institutionalized in many violent wild zones around the world, low-intensity wars also flare up as asymmetric conflicts between rich countries and poor peoples, Westernized nations and anti-Western movements, liberal democratic states and illiberal theocratic insurgents after 1989.
