Why Populists Love Dead Soldiers and Hate Live Officers
Right-wing populist leaders love soldiers (especially fallen ones) and the trappings of military life. But their love affair with the military rarely endures, writes Ronald Krebs in the latest issue of International Security.

Romanticizing and mythologizing the military solves a political problem for populists: how to mobilize people power without actually granting power to the people. This piece examines Bolsonaro’s Brazil; Modi’s India; the Law and Justice Party in Poland; Erdoğan’s Turkey; and Trump’s United States.
