The World's Biggest Group Project
Global politics is like a massive, ongoing group project where each student is a country. Some students are more powerful and want to lead, while others just want to protect their own work and get a good grade.
Imagine your school is a sovereign state. The headteacher has ultimate authority (sovereignty) within the school's gates. They can set rules (laws), manage the budget (economy), and decide on punishments (justice). Now, imagine a city-wide student council (an IGO like the UN) is formed. This council might issue guidelines on homework load or student welfare. The headteacher doesn't have to follow them, but if all other schools do, they might feel pressured to conform (loss of autonomy). Furthermore, if a global tech company (a TNC) provides all the school's computers, their software updates and policies can directly impact how lessons are taught, bypassing the headteacher's direct control. This shows how a state's sovereignty, while absolute in theory, is constantly negotiated and challenged by outside forces.
- 1
First, identify the core concepts in the source material. Look for explicit or implicit mentions of power, sovereignty, legitimacy, or interdependence.
- 2
Next, analyse the relationships between these concepts. For example, how is one state's exercise of hard power challenging another state's sovereignty?
- 3
Then, connect the source to your own detailed case studies. Use specific examples to support or challenge the claims made in the source.
- 4
Finally, construct a balanced argument. Evaluate the different perspectives presented and reach a clear, well-supported conclusion about the issue at hand.

Formal explanation with the rigour you need for the exam.
Understanding Power in Global Politics
Power is the currency of global politics. It's the ability to make others do what you want, whether they want to or not. Traditionally, power was seen as military might, but today we recognise a more complex spectrum.
Hard Power: The use of military and economic means to influence the behaviour or interests of other political bodies. This is a form of coercion. Examples include military intervention, coercive diplomacy, and economic sanctions.
Soft Power: The ability to attract and co-opt rather than coerce. It stems from the attractiveness of a country's culture, political ideals, and policies. Examples include cultural exports (films, music), educational exchange programmes, and a reputation for upholding human rights.
Smart Power: The effective combination of hard and soft power resources into an integrated strategy. It involves knowing when to use persuasion and when to use force, and how to combine them. For example, coupling development aid (soft) with the threat of sanctions (hard) to encourage political reform.
Sovereignty: The Bedrock of the International System
Sovereignty is the principle that a state has the exclusive right to govern its territory without external interference. It's the foundation of the modern state system, established by the Peace of Westphalia in 1648. However, in our interconnected world, the absolute nature of sovereignty is increasingly being questioned.
Internal Sovereignty: The supreme authority of a state within its own territory to make and enforce laws.
External Sovereignty: The recognition of a state's independence by other states and its ability to act as an equal on the world stage.
Challenges to Sovereignty: Globalisation, IGOs (like the EU, where members pool sovereignty), international law (e.g., human rights conventions), powerful transnational corporations (TNCs), and humanitarian interventions (R2P) all challenge a state's absolute control.
Interdependence and the Web of International Relations
No state is an island. Globalisation has created a complex web of interdependence, where the actions of one state can have profound consequences for others. This can be economic (trade, finance), political (alliances, security), or social (migration, cultural exchange). Interdependence can be a source of both cooperation and conflict, and it fundamentally alters how power and sovereignty operate.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
Source A is an excerpt from a speech by the foreign minister of Country X: 'We cannot stand by while the government of Country Y commits atrocities against its own people. The principle of Responsibility to Protect compels us to intervene, with or without a UN mandate. State sovereignty is not a licence to kill.'
Using the source and your own knowledge, analyse the tension between state sovereignty and humanitarian intervention.

A strong answer would be structured as follows:
Source B is a table showing the top 5 contributors to the United Nations regular budget for 2023:
- United States (22.00%)
- China (15.25%)
- Japan (8.03%)
- Germany (6.11%)
- United Kingdom (4.37%)
Using the source and your own knowledge, evaluate the claim that IGOs like the UN are primarily instruments of powerful states.

Glossary
Key terms for this topic — skim now; the Check step will test them.
- Power (in Global Politics)
The ability of a global actor to influence the actions of another global actor. It can be exercised in various forms, including hard, soft, and smart power.
- Sovereignty
The principle that a state has full authority and control over its own territory and people, free from external interference. It has internal (control within borders) and external (recognition by other states) dimensions.
- Hard Power
Achieving aims through coercion, typically involving military force ('sticks') or economic sanctions/inducements ('carrots'). Example: The US invasion of Iraq in 2003.
- Soft Power
Achieving aims through attraction and persuasion rather than coercion. It relies on cultural appeal, political values, and foreign policy legitimacy. Example: South Korea's global cultural influence (K-Pop, films).
- Smart Power
A strategic combination of hard and soft power resources to achieve foreign policy objectives. Coined by Joseph Nye, it emphasizes using the right tool for the context.
- Legitimacy
Refers to actors or actions that are considered acceptable and rightful. In global politics, it is crucial for justifying the exercise of power and upholding sovereignty.
- Interdependence
The mutual reliance between and among groups, organisations, and states for access to resources that sustain living arrangements. Economic and security interdependence are common forms.
- Intergovernmental Organisation (IGO)
An organisation composed primarily of sovereign states. Examples include the United Nations (UN), the European Union (EU), and the World Trade Organisation (WTO).
- Non-Governmental Organisation (NGO)
A non-profit, voluntary citizens' group which is organised on a local, national or international level. They are independent of government control. Examples: Amnesty International, Greenpeace.
- Unilateralism vs. Multilateralism
Unilateralism is a state acting alone, without the support of other states. Multilateralism is when states work together to address a common issue, often through IGOs.
- Responsibility to Protect (R2P)
A global political commitment endorsed by all UN member states in 2005 to prevent genocide, war crimes, ethnic cleansing and crimes against humanity. It can challenge traditional notions of state sovereignty by justifying international intervention.
