The Disintegrating World Order and Japan’s Pivotal Role

The international order, forged in the aftermath of World War II, is facing unprecedented strain. Recent actions by major global powers – the United States, China, and Russia – are challenging the established norms of sovereignty, peaceful dispute resolution, and international law. This erosion of order presents significant risks, potentially leading to a more unstable and dangerous world. Amidst this shifting landscape, Japan is being urged to strengthen its influence and contribute to rebuilding a rules-based international system, focusing on the Indo-Pacific region and promoting human security.

The Erosion of Post-War Principles

For eight decades, the post-World War II international order rested on fundamental principles: the sovereign equality of states, the peaceful settlement of disputes, and restraint in the leverage of force. Even as these principles were not always perfectly upheld – examples include the Soviet invasion of Czechoslovakia in 1968 and the U.S.-led invasion of Iraq in 2003 – a broad consensus existed among major powers regarding their importance.

However, this consensus is now fracturing. In January 2026, a U.S. Military operation resulted in the detention of Venezuelan President Nicolás Maduro and his wife, raising questions about the limits of intervention and respect for national sovereignty Stanford University analysis. This action, coupled with Russia’s earlier annexation of Crimea in 2014 and subsequent invasion of Ukraine, signals a willingness among major powers to disregard established international norms. China continues its assertive actions in the South China Sea, despite a 2016 international arbitral tribunal ruling against its claims.

The domestic political landscape within many nations, characterized by increasing social polarization since the 2008 financial crisis, has further exacerbated international instability.

The Rise of BRICS and Shifting Alliances

The emergence of new diplomatic arenas, such as the BRICS economic bloc (Brazil, Russia, India, China, and South Africa), reflects a changing global power dynamic. The BRICS summit in Brazil in July 2025 saw the inclusion of new members – Iran, Egypt, the United Arab Emirates, Ethiopia, and Indonesia – expanding its influence and presenting an alternative to the traditional Western-led international order Hudson Institute.

The Rio de Janeiro Declaration issued at the 2025 BRICS summit demonstrated Russia’s ability to leverage the bloc for its own purposes, condemning attacks on Russian infrastructure without explicitly addressing Russia’s actions in Ukraine. India’s endorsement of the declaration, despite its strategic partnership with the United States, highlights the complex calculations of emerging powers navigating a multipolar world. Internal dynamics within groups like the Shanghai Cooperation Organization (SCO) also reveal shifting alliances and priorities, as evidenced by disagreements over condemning terrorism in Jammu, and Kashmir.

Japan’s Role in a Changing World

As the international order erodes, the risk of a “might makes right” scenario increases, potentially leading to greater instability and conflict. Japan is uniquely positioned to play a crucial role in rebuilding a rules-based international system. Recognized as a trusted partner in Southeast Asia Mainichi Japan, Japan should leverage its influence to uphold the rule of law, secure maritime routes, and promote free trade under the banner of a Free and Open Indo-Pacific.

Beyond traditional security concerns, Japan should also champion “human security,” focusing on the protection of lives, livelihoods, and dignity. Investing in education and technological advancement is crucial for sustaining Japan’s national strength and strategic agency. Japan must prioritize the development of strong language skills, both Japanese and foreign languages, to enhance communication and collaboration in an increasingly interconnected world.
