Strategic Argument and Areas of Debate
The contemporary international system faces a profound structural paradox where the diffusion of global influence into complex multipolarity should theoretically incentivise cooperation, yet it is simultaneously destabilised by a aggressive resurgence of unilateralism among major powers. This concurrent fracturing creates a strategic vacuum that empowers emerging middle powers to act as crucial normative stabilisers and diplomatic mediators amidst the rapid erosion of the liberal international order.
Executive Summary
The global system has definitively transitioned from the post-Cold War unipolar dominance of the United States toward a fragmented multipolar configuration driven by states such as China, Russia, and India. However, this diffusion of power is violently disrupted by the unilateral policies of great powers, exemplified by the tariff wars initiated during the Donald Trump presidency and the widespread failure of the United Nations to enforce institutional norms during global crises. In response to this deteriorating liberal order, emerging middle powers such as Türkiye, Brazil, and Indonesia are adopting strategic autonomy and acting as norm entrepreneurs. Through collaborative platforms like the Astana Peace Process, these actors seek to mediate geopolitical friction and establish a reimagined normative framework capable of constraining unchecked great power rivalry.
Analytical Framework and Key Drivers
Complex Multipolarity and Power Diffusion: The international system has shifted away from the unipolarity seen after the Cold War into a multi-centric model driven by Asian economic growth. This structure diffuses influence among great powers and emerging actors, heavily complicating traditional global governance frameworks like the United Nations.
Resurgent Unilateralism Among Great Powers: Contrary to liberal institutionalist expectations, dominant states are increasingly bypassing multilateral institutions in favour of autonomous action. This behaviour, visibly accelerated during the Trump Administration starting in 2017, severely disrupts systemic cohesion and provokes retaliatory economic and diplomatic strategies.
Agency of Emerging Middle Powers: States such as Türkiye and Brazil operate beyond traditional Western alignments to project regional leadership and transform global governance structures. These actors utilise diplomatic agility to navigate competing geopolitical blocs like the BRICS network and the Shanghai Cooperation Organisation.
Norm Entrepreneurship and Systemic Stability: The creation and diffusion of shared operational principles by non-superpower states are essential to counteracting global fragmentation. Establishing a robust normative architecture acts as the primary mechanism to enforce accountability against unilateral violations, such as those formally addressed at the International Court of Justice.
Strategic Assessment & Empirical Findings
- The transition from bipolarity (1945–1989) to unipolarity (1989–2008) has conclusively shifted into a state of complex multipolarity following the systemic shocks of the 2008 global financial crisis.
- The unilateral economic policies of the United States, most notably the tariff and export control measures targeting China launched in 2018, have severely disrupted global supply chains and undermined institutional trust in the World Trade Organization.
- The credibility of the liberal international order has faced unprecedented erosion due to the failure of established mechanisms to halt Israel’s military actions in Gaza, despite an explicit interim measures ruling by the International Court of Justice.
- Emerging middle powers have effectively leveraged multipolarity to pursue simultaneous strategic alignments, balancing engagement between Western-led frameworks like the Quadrilateral Security Dialogue and non-Western structures such as the Shanghai Cooperation Organisation.
- Türkiye’s co-sponsorship of the Astana Peace Process alongside Russia and Iran demonstrates how pragmatic middle powers can successfully implement localised conflict mediation and manage refugee flows independent of traditional Western diplomatic channels.
Geopolitical Trajectories & Policy Risks
- The persistent normalisation of unilateralism by the United States severely weakens the collective authority of the United Nations, creating a structural vulnerability that emboldens states like China and Russia to expand their own alternative spheres of influence.
- Without a shared normative framework to regulate competition, the global economy faces a heightened risk of deep systemic fragmentation, threatening the export networks and supply chain dependencies of non-aligned middle powers like Brazil and Indonesia.
- The continued inability of international legal bodies such as the International Court of Justice to enforce compliance exposes a critical institutional impotence, potentially driving Türkiye and other regional powers to increasingly bypass Western architecture in favour of ad-hoc regional security coalitions.
Critical Policy Questions & Responses
Question 1 Why does the concurrent rise of multipolarity and unilateralism present a structural paradox for the United Nations and global governance?
Answer: While multipolarity inherently diffuses power and should theoretically incentivise collective decision-making, dominant actors like the United States are increasingly pursuing autonomous foreign policies that bypass institutional frameworks. This friction paralyses bodies such as the United Nations, transforming potential collaborative platforms into arenas of unchecked geopolitical friction and transactional diplomacy.
Question 2 How do the diplomatic strategies of emerging middle powers like Türkiye and Brazil challenge the traditional liberal international order?
Answer: Unlike traditional middle powers that historically reinforced Western institutional hegemony, emerging middle powers actively pursue strategic autonomy and norm-shaping behaviour outside established channels. By participating in alternative connectivity frameworks like the BRICS network and mediating regional conflicts directly, these nations promote a pluralist global architecture that reduces dependence on unipolar dictates.
Question 3 What are the long-term implications of the United States’ unilateral trade policies initiated in 2018 for global economic stability?
Answer: The aggressive deployment of tariffs and export controls targeting China fundamentally undermined the collaborative economic governance previously championed by the World Trade Organization. This retreat from multilateral trade norms accelerates systemic fragmentation, forcing intermediary states to rapidly diversify their supply chains and hedge against immense geopolitical market volatility.
Question 4 What does the international response to crises such as the war in Gaza reveal about the limitations of the current normative framework?
Answer: The failure to enforce compliance with the International Court of Justice interim rulings exposes a profound disconnect between the ideological claims of the liberal order and the actual behaviour of its principal architects. This institutional paralysis strips the system of its moral authority, demonstrating that without collective coercive pressure, established norms are incapable of restraining aggressive state behaviour.
