• Military Activities: Garuda Canti Dharma III 2026
  The U.S. Pacific Command, Indonesian National Armed Forces (TNI), and service members from 21 other partner nations participated in the Multinational Peacekeeping Exercise 2026 (MPE26) Garuda Canti Dharma III 2026 (GCD26) at the Indonesian Peacekeeping Training Center in Bogor, West Java, from July 20 through August 2, 2026. This exercise, involving over 700 personnel, is the final iteration funded through the U.S. Department of State's Global Peace Operations Initiative (GPOI).

• Defense Policy: Non-Aligned Stance Amidst Global Tensions
  On July 31, 2026, President Prabowo Subianto reaffirmed Indonesia's commitment to its free and active foreign policy, emphasizing a non-aligned position amidst rising global geopolitical tensions. Speaking to the Indonesian Chamber of Commerce and Industry (Kadin) in Jakarta, Prabowo stressed that Indonesia would not be drawn into military alliances or rival geopolitical blocs, advocating for a "good neighbor" principle.

• Diplomatic Relations: Mediation Offer for Korean Peninsula
  President Prabowo Subianto expressed Indonesia's willingness to mediate between North and South Korea, following a request from South Korea. Speaking on July 31, 2026, Prabowo stated that Indonesia is perceived as having no interest in meddling in other countries' domestic affairs, positioning it as a neutral broker.

• Security Incidents: Persistent Threats in Papua
  A Human Rights Watch report on July 29, 2026, highlighted concerns over military deployment in Merauke, Papua, related to the government's Integrated Food and Energy Estate project. This deployment has been linked to protests and the disappearance of a Papuan woman who had filed lawsuits against the project, raising human rights concerns. Earlier, on July 3, 2026, travel advice noted ongoing violence in Papua Pegunungan and Papua Tengah provinces, including attacks at remote airstrips and targeting foreigners.

• Counter-terrorism: Vigilance Maintained
  On July 27, 2026, Coordinating Minister for Political and Security Affairs, retired Gen. Djamari Chaniago, stated that Indonesia's terrorism threat is "relatively under control" but urged continued vigilance against evolving security risks. He noted that the Global Terrorism Index 2026 classifies Indonesia with a medium impact from terrorism, reflecting the effectiveness of prevention and law enforcement efforts.

• Cybersecurity: Ransomware and AI-related Abuse
  Indonesia recorded three ransomware victim listings between July 5-11, 2026, attributed to DeadLock, APT73/Bashe, and APT73, with no public data leaks reported. Additionally, an incident involving the misuse of free API credits on an AI-based video creation platform (varg.ai) was traced to Indonesia on July 29, 2026, using Chinese AI models. These incidents underscore the persistent and evolving nature of cyber threats targeting Indonesian entities.

Geopolitical Impact and Regional Dynamics

Indonesia's recent security and diplomatic activities reflect its strategic ambition to be a significant, yet non-aligned, player in the Indo-Pacific. The substantial defense acquisitions from Italy, India, and Turkey demonstrate a diversification of arms suppliers, moving beyond traditional sources and enhancing its strategic autonomy. This multi-vector approach to defense procurement signals Indonesia's intent to build a robust and modern military capable of safeguarding its vast archipelagic territory and strategic trade routes, without becoming overly reliant on any single major power. The acquisition of advanced missile systems from India, for instance, not only bolsters Indonesia's strike capabilities but also strengthens its defense ties with a key regional partner, potentially influencing the balance of power in Southeast Asia.

President Prabowo Subianto's consistent reiteration of Indonesia's "free and active" foreign policy and non-aligned stance is particularly pertinent amidst intensifying global rivalries involving the US, China, and Russia. This position allows Indonesia to engage with various powers without being constrained by alliance commitments, as exemplified by joint naval exercises with Russia in the Sea of Japan and multinational peacekeeping drills with the US and other partners. Such diplomatic agility enables Indonesia to pursue its national interests, foster regional stability, and potentially act as a neutral broker in international disputes, such as the offer to mediate between North and South Korea.

The ongoing conflicts in Ukraine, Gaza, Lebanon, and the Strait of Hormuz, as highlighted by President Prabowo, underscore a precarious global security environment that directly impacts Indonesia's strategic calculations, particularly concerning energy and food supply chains. Indonesia's cautious approach to contributing to a peacekeeping force in Gaza, despite US signals, further illustrates its pragmatic and independent foreign policy, prioritizing national interests and regional stability. Furthermore, Indonesia's efforts to strengthen maritime security cooperation with the Philippines and Vietnam in the South China Sea, though mentioned earlier in the year, remain a critical dynamic in managing regional tensions and asserting sovereign rights in contested waters.

Military and Defense Analysis

Indonesia's military modernization program is currently the largest in its history, aiming to replace aging assets and enhance capabilities across all domains. The recent contract for 12 Leonardo M-346F Block 20 light fighters will significantly upgrade the Indonesian Air Force's training and light attack capabilities, providing a crucial bridge for pilots transitioning to more advanced platforms like the Rafale and F-16. The acquisition of India's Astra Mk-1 air-to-air missiles and BrahMos cruise missiles represents a substantial boost to Indonesia's air combat and coastal defense capabilities, diversifying its armaments and potentially reducing reliance on Russian missile inventories for its Sukhoi fleet.

A landmark development is the commercial contract for 48 Turkish KAAN fifth-generation fighter jets and two İstif-class frigates. This deal not only introduces advanced platforms but also emphasizes technology transfer and the establishment of local aerospace infrastructure, signaling a long-term commitment to developing Indonesia's indigenous defense industry. The impending arrival of the Italian aircraft carrier Giuseppe Garibaldi, though a grant, will mark a historic milestone for the Indonesian Navy, providing unprecedented power projection capabilities, albeit requiring significant retrofitting and modernization. These acquisitions, coupled with increased defense spending (estimated at Rp185 trillion in 2026, up from Rp166 trillion in 2025), reflect a clear trend towards a more capable and technologically advanced force posture. The ongoing joint exercises, such as "Orruda 2026" with Russia and "Garuda Canti Dharma III 2026" with the US and other nations, are crucial for enhancing interoperability, refining operational tactics, and building trust with diverse international partners.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Indonesia will likely continue to finalize details and begin the implementation phases of its recent defense acquisitions. The arrival of the Giuseppe Garibaldi aircraft carrier in September 2026 will be a significant event, drawing considerable attention to the Indonesian Navy's evolving capabilities and the logistical challenges of integrating such a large vessel. Diplomatic efforts will remain focused on maintaining Indonesia's non-aligned stance while navigating complex global geopolitical currents. President Prabowo's offer to mediate in the Korean Peninsula dispute could see initial diplomatic overtures in the coming months. Cybersecurity vigilance will remain high, with ongoing efforts to counter ransomware and other digital threats.

Critical flashpoints and risk areas: The primary internal risk area remains Papua, where military deployments related to development projects continue to generate protests and human rights concerns. Any escalation of violence or further reports of human rights abuses could draw international scrutiny and destabilize the region. Externally, while Indonesia maintains a non-aligned policy, the intensifying competition between major powers in the Indo-Pacific, particularly in the South China Sea, poses a continuous challenge to maritime security and could lead to unforeseen diplomatic or security incidents. The Strait of Hormuz, as noted by President Prabowo, remains a critical flashpoint with potential global economic repercussions that could indirectly affect Indonesia.

Indicators to monitor: Key indicators to monitor include the progress of defense modernization programs, particularly the integration of new aircraft and missile systems, and the successful commissioning and operationalization of the Giuseppe Garibaldi. Any shifts in Indonesia's diplomatic engagement with major powers, especially regarding its non-aligned policy, should be closely watched. The frequency and severity of cybersecurity incidents, particularly those targeting critical infrastructure or government entities, will indicate the effectiveness of national cyber defenses. Developments in Papua, including protests, military actions, and human rights reports, will be crucial for assessing internal stability.

Strategic recommendations: Indonesia should continue to prioritize the development of its indigenous defense industry through technology transfer and local production, as seen with the Turkish KAAN deal, to enhance long-term self-reliance. Strengthening cybersecurity infrastructure and capabilities, including proactive threat intelligence sharing and incident response mechanisms, is paramount given the persistent and evolving digital threats. Diplomatic efforts should continue to leverage Indonesia's non-aligned position to foster dialogue and de-escalation in regional and global flashpoints, reinforcing its role as a constructive middle power. Internally, addressing the root causes of unrest in Papua through inclusive development and respecting human rights will be vital for long-term stability.
