Jakarta is facing growing pressure from within Indonesia to take a more assertive role in international diplomacy, specifically regarding the escalating conflict involving the United States, Israel and Iran. A diverse coalition of Islamic organizations and political figures are urging the government to move beyond its traditionally neutral stance and instead lead a coalition of Muslim-majority nations in a push for de-escalation. This shift reflects a rising expectation that Indonesia, the world’s largest Muslim-majority country, should leverage its influence to address the crisis, particularly following a recent surge in violence in March 2026.
The calls for action aren’t coming from a single faction. Instead, they represent a rare alignment across Indonesia’s religious, political, and academic landscapes. This convergence underscores a growing frustration with what many see as insufficient international efforts to contain the conflict and a belief that Indonesia’s unique position – a nation with a strong Islamic identity and a history of non-alignment – gives it a moral authority to act. The core of the argument centers on Indonesia’s “independent and active” (bebas aktif) foreign policy, a principle enshrined in its diplomatic approach, and how it can be applied to this increasingly volatile situation.
Calls for a Stronger Diplomatic Response
The Majelis Ulama Indonesia (MUI), the country’s top Islamic clerical body, has been among the most vocal proponents of a more robust response. The MUI has condemned actions taken by the U.S. And Israel as violations of international law and has called for a stronger diplomatic response from Jakarta. Notably, the MUI has also advocated for Indonesia’s withdrawal from the U.S.-linked “Board of Peace” (BoP), arguing that the initiative has lost its credibility as a neutral platform for dialogue. According to the MUI, the BoP’s perceived bias undermines its ability to facilitate meaningful de-escalation efforts.
Indonesia’s two largest Islamic organizations, Nahdlatul Ulama (PBNU) and Muhammadiyah, while stopping short of explicitly endorsing confrontation, have echoed the call for greater engagement. PBNU, led by Yahya Cholil Staquf, has urged the government to utilize its existing diplomatic channels and its role in multilateral initiatives to press for de-escalation. NU figures have also suggested exploring outreach to Tehran and leveraging Indonesia’s leadership within the D-8 Organization for Economic Cooperation – a group of eight developing Muslim-majority countries – as a foundation for building a broader coalition. The D-8’s stated goals include promoting economic cooperation and enhancing the collective bargaining power of its member states. More information about the D-8 can be found on their official website.
Muhammadiyah, another influential Islamic organization, has emphasized diplomacy as the sole viable path forward. They are calling for intensified coordination with international institutions like the United Nations and the Organization of Islamic Cooperation (OIC), while simultaneously urging all parties involved in the conflict to exercise restraint. Muhammadiyah’s stance reflects a preference for a multilateral approach, utilizing established international frameworks to address the crisis.
Beyond Religious Organizations: Parliamentary and Policy Support
The push for a more assertive Indonesian role isn’t limited to religious organizations. Policy groups, such as the Center for Islamic Studies in Finance, Economics, and Development (CISFED), have also weighed in, arguing that Indonesia’s bebas aktif foreign policy provides a strong foundation for taking on a more prominent role. CISFED suggests Indonesia should act as a convener of neutral states, rather than attempting to mediate alone, to reduce tensions.
Within the Indonesian parliament, lawmakers from both the Indonesian Democratic Party of Struggle (PDI-P) and the Prosperous Justice Party (PKS) have echoed similar sentiments. They are urging President Prabowo Subianto to adopt a firmer and more independent stance on the issue. Some parliamentarians have explicitly called for Indonesia to spearhead a coalition of non-aligned Muslim-majority nations, believing this would amplify Jakarta’s voice on the international stage. President Subianto’s office has not yet issued a formal response to these calls, but sources within the administration indicate the issue is under active consideration.
From Mediator to Coalition Builder: Challenges and Opportunities
The growing chorus of voices advocating for a more proactive Indonesian role signals a shifting expectation of Jakarta’s place on the global stage. Rather than simply acting as a traditional mediator with limited leverage, Indonesia is being encouraged to organize and lead a broader coalition capable of amplifying diplomatic pressure. This approach could allow Indonesia to translate its moral standing into collective influence, mobilizing support across the Muslim world and the Global South without overextending its geopolitical reach.
However, significant challenges remain. While Indonesia enjoys credibility as a non-aligned actor, it lacks the direct leverage over key players – the United States, Israel, and Iran – that would be necessary to broker a decisive agreement. The conflict is deeply rooted in complex geopolitical rivalries, and Indonesia’s influence is limited in that context. Its potential role may lie less in brokering a peace deal and more in mobilizing a coalition of neutral voices, shaping global opinion, and reinforcing calls for de-escalation. This would involve leveraging its diplomatic network, its position within organizations like the OIC, and its moral authority to build a consensus for a peaceful resolution.
As domestic pressure intensifies, the challenge for President Subianto’s administration will be to translate these expectations into a form of diplomacy that is both credible and effective, without overextending Indonesia’s reach on one of the world’s most complex geopolitical fault lines. The next key step will likely be a formal statement from the President outlining his administration’s approach to the crisis, expected following a scheduled cabinet meeting on foreign policy in late April 2026.
This developing situation warrants continued attention. Readers interested in staying informed can follow updates from the Indonesian Ministry of Foreign Affairs on their official website and monitor reporting from Reuters and the Associated Press for further developments.
