How to Choose the Right International Relations Dissertation Topic
The strongest topics sit at the intersection of a live policy debate and literature you can actually access — journal articles, government reports, NGO publications — within the time available before your deadline.
Speak to your supervisor early about scope, confirm that primary sources exist for your chosen case study, and avoid topics so broad — such as “the future of NATO” — that they cannot be answered within 8,000 to 12,000 words.
If you’re still unsure, a structured dissertation proposal can pressure-test your research question, methodology and literature review before you commit to full-scale writing.
