This lesson examines the different types of intervention — diplomatic, economic and military — that the international community uses to respond to human rights violations, conflict and humanitarian crises. It addresses the Edexcel Enquiry Question: "What is the role of global governance in promoting development and human rights?" This is one of the most politically charged and academically debated areas of the specification, requiring careful analysis of competing principles: state sovereignty versus the responsibility to protect.
Intervention refers to actions taken by external actors (states, coalitions, international organisations) to influence the internal affairs of another state. The spectrum of intervention ranges from gentle diplomatic persuasion to full-scale military invasion. The key tension is between two fundamental principles of the international system:
These two principles frequently conflict: when a government commits atrocities against its own people, does the international community have the right — or even the duty — to intervene, or does sovereignty make this impermissible? This tension has produced some of the most significant and controversial events in modern history.
Diplomatic intervention involves using negotiation, mediation, condemnation and persuasion to influence state behaviour without using force or economic coercion:
Strengths: Non-violent, respects sovereignty, can build consensus, low cost. Weaknesses: Easily ignored by determined violators, slow, often ineffective without the threat of further action, depends on international unity.
Sanctions restrict economic activity with a target country to pressure its government into changing behaviour:
| Sanctions Case | Target | Duration | Outcome |
|---|---|---|---|
| South Africa (anti-apartheid) | Apartheid regime | 1960s–1994 | Contributed to end of apartheid (alongside domestic resistance and economic pressure) |
| Iran (nuclear programme) | Iran's government | 2006–ongoing | Led to 2015 nuclear deal (JCPOA), but reimposed by USA in 2018; Iran's economy severely damaged |
| Russia (Ukraine invasion) | Russian economy, oligarchs | 2014–ongoing (intensified 2022) | Significant economic impact (GDP contracted 2.1% in 2022; rouble crashed; capital flight) but war continues |
| North Korea (nuclear weapons) | North Korean regime | 2006–ongoing | Have not prevented nuclear development; devastating impact on civilian population; regime survives |
| Cuba (US embargo) | Cuban government | 1962–ongoing | Longest-running sanctions regime; significant humanitarian impact but communist regime persists |
| Myanmar (post-2021 coup) | Military junta | 2021–ongoing | Limited impact; junta retains power; civilian suffering increased |
The humanitarian cost of sanctions: Comprehensive sanctions often harm civilian populations more than the targeted regimes. The Iraq sanctions (1990–2003) are estimated to have contributed to 500,000 excess child deaths (a contested figure based on varying methodologies, but the humanitarian impact was undeniable). UNICEF reported that the under-five mortality rate in Iraq roughly doubled during the sanctions period. This experience led to a decisive shift towards targeted ("smart") sanctions that aim to hurt elites while minimising civilian impact — though even targeted sanctions have significant economic ripple effects.
Exam Tip: When evaluating sanctions, always discuss both effectiveness and humanitarian impact. The best answers acknowledge that sanctions can be a useful tool of pressure but often have unintended consequences for civilian populations, and that their effectiveness depends on international unity and the nature of the target regime.
Military intervention involves the use of armed force by one or more states (or an international organisation) within the territory of another state:
The Responsibility to Protect is a political commitment adopted unanimously by all UN member states at the 2005 World Summit. It emerged directly from the failure to prevent the Rwandan genocide (1994) and the Srebrenica massacre (1995). It established three pillars:
