The ANZUS treaty, a security pact between Australia, New Zealand, and the United States established in 1951, has had various indirect effects on the Southeast Asian region, including Indonesia. Although Indonesia is not a formal member of ANZUS, the presence of this trilateral alliance in the Asia-Pacific region has significantly influenced Indonesia’s geopolitical considerations, defense posture, and diplomatic strategies. Over the decades, the impact of ANZUS on Indonesia has evolved, shaped by shifting regional tensions, military cooperation patterns, and Indonesia’s foreign policy principles such as non-alignment.
Background of ANZUS and Its Regional Presence
Formation and Purpose of ANZUS
The ANZUS (Australia, New Zealand, United States Security Treaty) was created in the aftermath of World War II to provide a collective defense mechanism against potential aggression in the Pacific. Its primary aim was to ensure security cooperation and military support among the three nations, especially in the context of rising Cold War tensions. While the alliance initially centered around the Pacific region, its implications extended more broadly to include Southeast Asia.
Strategic Location of Indonesia
Indonesia, situated between the Indian and Pacific Oceans, holds a vital position in global maritime routes and regional stability. Its proximity to Australia and the Southeast Asian mainland means that any shift in defense strategy by ANZUS members inevitably involves consideration of Indonesia’s position and policies. This proximity has led to both opportunities for cooperation and areas of friction.
Impact on Indonesia’s Foreign Policy
Non-Alignment and Regional Neutrality
Indonesia’s traditional stance has been rooted in a foreign policy of non-alignment. As a founding member of the Non-Aligned Movement (NAM), Indonesia has consistently aimed to avoid entanglements in major power rivalries. The existence of ANZUS, a military alliance led by the United States, has sometimes presented challenges for Indonesia in maintaining a balanced diplomatic posture, especially during the Cold War era when ideological divisions were sharp.
Regional Leadership Aspirations
The influence of ANZUS in the region occasionally appeared to overshadow Indonesia’s ambitions for regional leadership. Indonesia has long positioned itself as a leading voice in ASEAN and has sought to build regional autonomy in security matters. The continued presence of external military alliances like ANZUS has at times been viewed as a constraint to those ambitions, pushing Indonesia to strengthen ASEAN-led security initiatives such as the ASEAN Regional Forum (ARF).
Security Concerns and Cooperation
Shared Interests in Maritime Security
Despite ideological differences, Indonesia and ANZUS members, particularly Australia and the United States, share several strategic concerns, especially in the areas of maritime security and counterterrorism. The Strait of Malacca, one of the world’s busiest maritime chokepoints, is of critical interest to all parties. Cooperation in patrolling and securing sea lanes has indirectly benefited Indonesia, even if it occurred under the broader framework of ANZUS-inspired operations.
Military Exercises and Intelligence Sharing
Indonesia has participated in joint military exercises and training programs with ANZUS countries, most frequently with Australia and the U.S. These exercises have enhanced Indonesia’s military capabilities and interoperability with foreign forces. Though not under the ANZUS framework directly, these collaborations are influenced by the strategic agendas of ANZUS members and reflect the alliance’s broader security objectives in the Indo-Pacific.
Geopolitical Implications for Indonesia
Response to Regional Power Rivalries
With the rise of China and growing U.S.-China rivalry, ANZUS has gained renewed importance as part of broader Indo-Pacific security frameworks. For Indonesia, this creates a strategic dilemma. On the one hand, the alliance could help maintain regional stability, which benefits Indonesia’s trade and security. On the other hand, overt alignment with any bloc risks compromising Indonesia’s independent foreign policy stance and could provoke diplomatic friction with other major powers, including China.
Influence on Defense Modernization
Indonesia’s awareness of the military capabilities and strategies employed by ANZUS members has influenced its own defense modernization efforts. The country has prioritized improving its air and naval capabilities, often inspired by regional defense standards that are shaped in part by ANZUS members. Military procurement decisions and training models occasionally reflect technologies and doctrines shared through exposure to ANZUS-aligned forces.
Impact on Bilateral Relations
IndonesiaAustralia Relations
Australia, being geographically closest to Indonesia among the ANZUS members, has had a complicated yet vital relationship with Indonesia. While the two countries have collaborated in areas like disaster relief, counterterrorism, and border security, tensions have occasionally flared over spying allegations or military exercises. Nevertheless, the security cooperation remains strong and often mirrors the strategic thinking influenced by Australia’s role within ANZUS.
IndonesiaUnited States Engagement
The U.S. has consistently engaged Indonesia in security dialogues, arms sales, and military training. While these efforts are part of broader bilateral relations, they also serve the larger strategic interests of the ANZUS alliance in countering regional threats and maintaining balance. American naval presence in the region, sometimes in coordination with Australia, indirectly enhances Indonesia’s maritime security posture.
Public Perception and Political Sensitivities
Domestic Opinion on Foreign Military Presence
Within Indonesia, public opinion tends to be cautious about foreign military alliances and interventions. This sentiment is rooted in the country’s colonial past and its emphasis on sovereignty and independence. Any perceived alignment with foreign military pacts like ANZUS is met with scrutiny, pushing Indonesian policymakers to tread carefully in their diplomatic and defense engagements.
Media and Academic Discourse
Scholars and analysts in Indonesia often debate the implications of alliances like ANZUS. While some view it as a stabilizing force in an increasingly contested Indo-Pacific region, others argue that it promotes militarization and diminishes ASEAN centrality. The debate reflects broader concerns about the future of regional security architecture and Indonesia’s role within it.
Although Indonesia is not a member of the ANZUS alliance, its strategic location and regional influence mean that it cannot remain untouched by the alliance’s presence and activities. The impact of ANZUS on Indonesia is multifaceted ranging from defense cooperation and maritime security to geopolitical calculations and foreign policy balancing. While it brings certain benefits, such as increased military professionalism and regional stability, it also challenges Indonesia’s principle of non-alignment and regional autonomy. Moving forward, Indonesia is likely to continue engaging pragmatically with ANZUS members, all while reinforcing its independent role in shaping Southeast Asia’s security landscape.
