POWER 50 is fifty capsules across fifty days — the whole PSIR syllabus revised once, in the order the syllabus is actually built. One topic a day: read the capsule, write the same day, don’t break the chain. Running alongside it are PSIR Dynamics 2026 and the PYQ Vault, which puts 560 previous-year questions in front of you across the same fifty days — roughly eleven a day.
Day 32 — Key Concepts in International Relations
Day 32 opens the International Relations section of Paper II with the vocabulary the rest of the paper is written in: national interest, power, security, balance of power, deterrence, transnational actors and collective security. The capsule takes each concept as the paradigms actually contest it — Morgenthau’s interest defined in terms of power against Wendt’s socially constructed interest; Robinson’s six categories; hard, soft, smart, sharp and fast power; polarity and the stability debate from Waltz to Mearsheimer. From there it moves through the balance of power — the Congress of Vienna to Walt’s balance of threat, Schweller’s balance of interest and soft balancing — then deterrence and MAD, with Waltz’s “more may be better” set against Sagan’s organisational pessimism, and security read as both the security dilemma (John Herz) and Brian Job’s insecurity dilemma, widening into human security and securitization. It closes with complex interdependence, MNCs, NGOs and the crisis of the nation-state; collective security, R2P and the world capitalist economy; and a revision kit of power quotes and a scholar index. Between 2016 and 2025, this unit carried 4 × 10-markers, 7 × 15-markers and 3 × 20-markers — fourteen questions in ten years.
Notice what UPSC actually does with this vocabulary. Balance of power is “notoriously full of confusion.” National interest is “essentially contested.” Collective security and R2P are similar but not the same. Each of those is a question about a definition — which is why the vocabulary has to be exact before the argument can get interesting.
Write before the evening:
- Explain the concept of balance of power. What are the various techniques of maintaining balance of power? (UPSC 2020, 20m)
- Collective security and Responsibility to Protect (R2P) are similar but different in scope, goals and methods. Explain. (UPSC 2025, 15m)
- National Interest is an essentially contested concept. Comment. (UPSC 2022, 10m)
If you go blank on a point — a scholar, a definition, one of the modifications of the balance-of-power thesis — it is covered in full in your Foundation and OGP class notes and handouts. Revise it, then write.
