States first: the realist focus on the primary actor

Realism is famously state-centric. States have sovereignty, territory, and enforcement power. In realist logic, NGOs and international organisations can matter, but they cannot ultimately guarantee security in the same way a state can.

That is why realism fits so naturally into IB Global Politics questions on war, deterrence, alliances, and rivalry. When you feel lost in a stimulus, anchor your analysis back to state interests: Who gains security? Who loses strategic depth? Who feels threatened?

Power and the security dilemma (the most testable duo)

Realists treat power as practical insurance. Military capability, economic leverage, and strategic alliances are ways to reduce vulnerability.

But there is a trap: the security dilemma. When one state increases its military capabilities to feel safer, others may interpret it as preparation for aggression and respond in kind. Everyone becomes less secure, even if no one intended conflict.

To tighten your terminology around power, use Types and definitions of power - IB Notes.

Institutions and ideals: why realists stay sceptical

Realists are not saying cooperation never happens. They are saying cooperation is usually conditional. Institutions can facilitate agreements, but they do not erase anarchy. When interests shift, commitments can weaken.

For IB Global Politics evaluation, this is gold: realism explains patterns of conflict and competition well, but it can underplay norms, identities, and the growing influence of non-state actors.

How to use realism in IB Global Politics exam answers

In IB Global Politics, realism earns marks when it is used as a tool, not a label. A strong paragraph usually does three things:

1. Apply: connect a real-world action to anarchy, security, or power.

2. Explain: show the causal logic (fear, vulnerability, deterrence, relative gains).

3. Evaluate: note what realism misses (norms, institutions, domestic politics, identity).

Conclusion: make realism your default lens, then evaluate it

Realism is often the fastest way to explain why states compete, arm themselves, and sometimes choose force even when the costs are obvious. For IB Global Politics, treat it like your first pair of glasses: put it on, interpret the event through power and security, then switch lenses to evaluate what realism cannot explain.

To turn that into marks, combine RevisionDojo’s Study Notes, Flashcards, and AI Chat with the Questionbank and Grading tools for feedback-driven practice.
