Reddit mentions of Theory of International Politics

Alright then, my "standard suggestions":

• Introduction to International Relations: Theories and Approaches - Robert Jackson, Georg Sørensen
  
• Theory of International Politics - Kenneth N. Waltz
  
• Social Theory of International Politics - Alexander Wendt
  
• Power & Independence - Joseph Nye, Robert Keohane
  
• The Tragedy of Great Power Politics - John Mearsheimer
  
• Man, the State, and War: A Theoretical Analysis - Kenneth N. Waltz

I would also recommend The Globalization of World Politics as an introductory text to the field. It's an absolutely phenomenal textbook, while summaries you've posted are indeed comprehensive and succinct.

To elaborate, with more comprehensive texts (should the OP choose to read them), IR is a broad field. But specifically regarding International Politics, I would recommend Nye's The Future of Power, as a current perspective on international power (and the fairly recent differentiation in power resources, eg. "hard" and "soft" power). Focusing specifically on International Politics (as opposed to other IR subfields like development), the seminal works for the current theories on international politics include:


Theory of International Politics by Kenneth N. Waltz (1979), which serves as the foundation for structural realist (or neorealist) school. Neorealists are generally split between offensive realists (like Mearsheimer) and defensive realists (Waltz and Walt) as general categorizations, and you can find related works from these scholars for a focused view from either on the issues they disagree upon.

After Hegemony (1984) by Robert Keohane is the neoliberal institutionalist response to Waltz (Power and Interdependence by Keohane & Nye (1977) is probably its founding text), and one of the leading works of the theoretical field itself.

Finally, Social Theory of International Politics by Alexander Wendt (1999) is the comprehensive overview of the social constructivist school.

These largely cover all the major theoretical branches of current International Political theory (without diverging too heavily into IR subfields), though I do emphasize that these classifications are fairly fluid, given the readiness of offensive realists like Mearsheimer to look into the "black box" of domestic politics in the (highly controversial) piece, The Israel Lobby and US Foreign Policy. Again, these are the main theoretical works in these respective schools, and it is not necessary for you (the OP) to read through all of them to understand the subject.

While not exclusively International Politics focused, World Systems Theory is highly influential critical theory for IR studies, and understanding it (and Marxist-influenced dependency theory) as well as game theory (Nash Equilibrium etc) are both integral to modern IR methodologies and theories. By in large, Hobbes and the Leviathan (and a bit of Rousseau) is the only political theory that you need to start delving into IR theory, so you should be good on that front.

There are also specialized and diversified IR fields such as Development, Peace and Conflict Resolution, and Human Rights, but those are most likely not necessary given the scope of your conference (by the sounds of it, predominantly focused on state-centric International Politics).

Honestly, I haven't come across a ton of good textbooks explaining the basics of IR theory. The Wikipedia page is a pretty good starting point for the big theoretical schools.

Neorealism and Its Critics is also a modern classic on IR theory you'd read in most college or graduate level IR courses. Waltz's Theory of International Relations is also a seminal text. Sam Huntington's "Clash of Civilizations" Article and Book were both extremely important to recent thinking on IR.

Kenneth Waltz writes a lot on international theory. He's a big name in IR scholastics.

Basically, there's realism, liberalism and constructivism... most of the additional theories are just updates or adjustments to those main theories. They all refer to how actors (states, individuals, groups) in the world interact.
