What is the common examiner trap about Intl. Relations in UPSC exams?

They may ask about the 'enforcement mechanism' of international law (weak/consent-based) versus domestic law (strong/coercive). They might swap the names of treaties (e.g., INF Treaty vs New START) or conflate the International Court of Justice (ICJ) with the International Criminal Court (ICC).

What should UPSC aspirants remember about Intl. Relations for Prelims?

1. Target this Treaty: UNCLOS (United Nations Convention on the Law of the Sea) - one of the most widely ratified treaties. 2. Target this Legal Principle: UN Charter Article 2(4) - prohibition on the use of force. 3. Target this Case: 2016 Permanent Court of Arbitration ruling against China's 'nine-dash line' claim in the South China Sea.

What This Article Covers

Crisis of Enforcement

The article posits that international law is in crisis due to a lack of enforcement against powerful states, rendering key treaties like the UN Charter and UNCLOS ineffective.

🌍

Global Pattern of Violations

It cites violations across multiple continents, including Russia in Ukraine, U.S. actions in Iraq and Iran, China in the South China Sea, and conflicts in Syria, Yemen, and Ethiopia.

📉

Weakening Regimes

Beyond use of force, the article notes the erosion of arms-control (INF Treaty), human rights, and environmental (Paris Agreement) regimes, threatening global stability.

Detailed Analysis & Strategic Depth

Context / Background

The article critiques the post-WWII 'rules-based international order' built on treaties like the UN Charter (1945), Geneva Conventions, and UNCLOS (1982). This system, designed to curb state anarchy through collective security and international law, is now fraying. The context is a shift from a principle-based to a power-based world order, reminiscent of pre-Westphalian or Cold War dynamics, where geopolitical rivalry overrides legal norms.

Core Analysis & Implications

The analysis identifies a pattern of impunity: 1) Use of Force: Breaches of UN Charter Article 2(4) by major (Russia, U.S.) and regional powers (Turkey, Azerbaijan). 2) Maritime Law: China's actions in the South China Sea defy the 2016 PCA ruling, undermining UNCLOS. 3) IHL & Human Rights: Atrocities in Syria, Yemen, Tigray, Gaza, and Xinjiang highlight the failure of accountability mechanisms like the ICC. 4) Regime Collapse: The unravelling of the INF Treaty, JCPOA, and climate commitments signals a retreat from multilateral cooperation. The implication is a more unstable, conflict-prone world where trust between nations evaporates and global commons are degraded.

Future Outlook / Way Forward

The article suggests the solution lies in strengthening multilateral institutions and accountability mechanisms. However, it acknowledges the core challenge: international law relies on state consent and is paralyzed by Security Council vetoes. The way forward involves cultivating a global political culture of restraint and recognizing international law as a framework of shared expectations, even if imperfectly enforced. For India, this underscores the importance of strategic autonomy and reformed multilateralism as key foreign policy pillars.
