Alliance Embeddedness: Rodrigo Duterte and the Resilience of the US–Philippine Alliance

In 2016, Philippine President Rodrigo Duterte pledged to radically reorient Philippine foreign policy by separating from Manila's longtime ally the United States. Yet, this vaunted break with America has failed to manifest. Joint US–Philippine military activities have continued with President Duterte even singing the praises of his American partners. To understand how this about-face in Manila occurred, I conducted a detailed analysis of the first eighteen months of the Duterte administration. Drawing on primary sources and interviews with government officials from both countries, I argue that the continued vitality of the US–Philippine alliance stems not from disenchantment with China nor personal relationship between Duterte and Trump, but rather from an underlying institutional affinity engendered over decades of defense cooperation. Specifically, institutionalized cooperation within the alliance has cultivated a strong reservoir of support for the alliance within key institutions inside the Philippine government. This case not only highlights the development of the Duterte administration but also illustrates the wider ability of alliances to weather political discord by cultivating support within national bureaucracies.
