Analyse how the scope of International Relations has expanded with the rise of non-state actors in global politics.

Introduction

For three centuries after the Peace of Westphalia (1648), International Relations studied mainly the relations of sovereign states: war, diplomacy and alliances. Since the 1970s, and especially after the Cold War, a wide range of non-state actors has entered global politics. Their rise has broadened what IR studies, how it explains events, and even how it defines power and security.

Traditional scope

Classical realism treated states as unitary, rational actors pursuing power in an anarchic system. Issues of "high politics" — security and diplomacy — dominated, while economic and social affairs were considered "low politics". Individuals and private groups mattered only as subjects of states.

Types of non-state actors

Intergovernmental organisations such as the UN, IMF, World Bank and WTO set rules, finance development and settle disputes. Multinational corporations command budgets larger than many states; technology firms now control data, communication platforms and even satellite networks that matter in wars. NGOs such as Amnesty International, Médecins Sans Frontières and environmental groups shape norms and monitor states, often through what Keck and Sikkink called transnational advocacy networks. Violent non-state actors — al-Qaeda, ISIS, the TTP — wage war across borders, while private military companies sell force. Individuals and diaspora communities, empowered by social media, influence opinion and policy worldwide.

How the scope has expanded

New issues. IR now studies trade, finance and debt, climate change, pandemics, migration, human rights and cyberspace. The 2008 financial crisis, COVID-19 and the Paris Agreement showed that these issues are as consequential as wars.

New theories. Keohane and Nye's Power and Interdependence (1977) introduced complex interdependence, with multiple channels connecting societies and no fixed hierarchy of issues. Constructivists explained how NGOs and norms change state behaviour, for example in the campaign to ban landmines (Ottawa Treaty, 1997). The study of global governance examines how states, organisations, companies and civil society regulate global problems together.

New concepts of security and sovereignty. Terrorism by non-state groups led to the "war on terror" and debates on pre-emption and drone strikes. Human security, introduced by the UNDP's 1994 Human Development Report, shifted the focus from states to people. Doctrines such as the Responsibility to Protect (2005) qualified absolute sovereignty. Financial bodies such as the FATF can pressure states over terrorist financing.

Limits

The state has not withered away. States still control armies, borders, taxes and legal recognition; non-state actors often work through or against states rather than replacing them. The return of great-power rivalry, the Russia–Ukraine war and US–China competition show that state power remains central. The modern view is therefore one of a mixed-actor system.

Implications for Pakistan

Pakistan faces violent non-state actors on its western border, operates under IMF programmes and FATF scrutiny, depends on remittances from a large diaspora, and must deal with global technology platforms and information warfare. Its foreign policy therefore needs economic diplomacy, engagement with international organisations, counter-terrorism cooperation and a strategy for the digital domain alongside traditional security.

Conclusion

The rise of non-state actors has transformed IR from a narrow study of inter-state power into a broad discipline covering economics, environment, technology, norms and human security. States remain the primary actors, but they now share the stage with organisations, companies, networks and individuals — and no serious analysis of global politics can ignore them.
