Given China and Russia’s increasingly aggressive behaviour, balance of threat theory posits that formal US allies should close ranks behind the United States. The literature on alliance politics reinforces this logic by showing that alliances deter aggression and reduce the occurrence of war. Recent developments, however, have somewhat undermined these claims, as the president of the Philippines, Rodrigo Duterte, and the president of Turkey, Recep Tayyip Erdogan, publicly threatened to break ranks with Washington and to realign with China and Russia respectively. How can we make sense of such defiant behaviour? This article argues that populist blackmail elucidates this phenomenon and compares it to three alternative propositions: conventional bandwagoning, bandwagoning for profit, and hard hedging. Based on empirical evidence, the article reveals that the provocative statements of Duterte and Erdogan were not a genuine push for realignment with Beijing and Moscow, but rather political strategies designed to enhance their bargaining power with Washington in the hopes of securing certain concessions, while simultaneously galvanising domestic support to justify their raison d’être and to secure their hold on power. Furthermore, the article infers that two concomitant factors – political grievances and the perceived lack of security assurance – propelled both presidents to resort to blackmail.
