Indonesian-U.S. Military Ties

The relationship between Indonesia’s armed forces and the United States military has moved through distinct phases over the past several decades, shaped as much by human rights considerations in Washington as by shared strategic interests in Southeast Asia. During the Cold War, the two militaries maintained close training and cooperation ties, with Washington viewing Indonesia’s armed forces as a bulwark against communist influence in the region and a stabilizing force in the world’s largest Muslim-majority nation.

That relationship came under sustained strain in the 1990s, as reports of serious human rights abuses committed by Indonesian security forces, particularly in East Timor, Aceh, and Papua, drew increasing scrutiny from the US Congress. The violence surrounding East Timor’s 1999 independence referendum proved to be a turning point: militia groups widely understood to have military backing carried out a campaign of destruction and killing in the territory’s aftermath, prompting Washington to suspend most forms of direct military assistance and training in response.

The suspension remained largely in place for the following decade, becoming a recurring point of friction between the two governments even as broader diplomatic and economic ties continued. Advocates for restoring cooperation argued that isolating the Indonesian military made it harder to encourage internal reform and professionalization, while critics warned that resuming assistance without clear accountability for past abuses would send the wrong signal both to Jakarta and to victims still seeking justice.

Crisis Insights followed this debate closely as successive US administrations weighed competing priorities, counterterrorism cooperation after the early 2000s, growing strategic interest in balancing China’s regional influence, and continued concern about accountability for past abuses, against one another. Gradual, incremental steps toward restoring military ties took place over the 2000s and 2010s, typically tied to specific human rights benchmarks or narrowly scoped forms of cooperation rather than a full, unconditional resumption of the earlier relationship.

By the following decade, the two countries had rebuilt a substantial defense relationship, including joint exercises and expanded security dialogue, reflecting Indonesia’s growing strategic importance as the largest economy and most populous nation in Southeast Asia. Even so, memories of the 1999 suspension have continued to shape how both governments approach military cooperation, with periodic congressional attention to unresolved human rights cases serving as a reminder that the relationship’s earlier rupture was never entirely forgotten, even as practical cooperation expanded.

Within Indonesia itself, the debate over military reform ran on a parallel track to the diplomatic back-and-forth in Washington. Civilian oversight of the armed forces expanded gradually after the end of the Suharto era, with the military formally relinquishing its long-held reserved seats in the national legislature and stepping back, at least on paper, from the direct territorial administrative role it had exercised for decades. Reform advocates within Indonesia argued that renewed international engagement, conditioned properly, could reinforce this internal reform trajectory rather than undermine it, a view that gradually gained traction among a new generation of Indonesian defense officials less tied to the institutional habits of the authoritarian period.

The specific legal mechanisms used to restrict cooperation illustrate how granular this relationship became. Legislative provisions tied certain forms of assistance to specific accountability benchmarks, prosecutions or disciplinary action in individual human rights cases, creating a framework in which cooperation could be selectively restored piece by piece rather than through a single blanket decision. This incremental approach frustrated advocates on both sides: those pushing for faster normalization viewed it as overly cautious, while human rights organizations warned that incremental restoration risked eroding leverage before accountability had meaningfully advanced.

Our coverage of this issue has emphasized that the trajectory of military-to-military ties between the two countries offers a broader case study in how human rights conditionality interacts with strategic interest over long timeframes. Even as counterterrorism cooperation and, later, competition with China’s regional presence pushed successive administrations toward deeper engagement, the historical memory of 1999 continued to inform how closely each new step was scrutinized.

The episode also carries lessons that extend well beyond the Indonesia-US relationship specifically. Security assistance conditioned on human rights performance has become a more common tool in Washington’s broader foreign policy toolkit since the 1990s, and the Indonesian case is frequently cited, by both proponents and skeptics of conditionality, as evidence for competing conclusions about whether such leverage actually produces meaningful institutional reform or simply drives a partner country toward alternative suppliers of military training and equipment. Indonesia’s own gradual diversification of defense partnerships in the years following the suspension lent some support to the latter view, even as human rights advocates maintained that the pressure had still meaningfully shaped internal reform debates within the Indonesian military itself.
