Overview
This lecture covers why South Africa developed nuclear weapons and then chose to dismantle them, exploring the roles of domestic politics, international relations, and national security in these decisions.
Factors Behind Nuclear Weapon Acquisition
- Domestic politics, international relations, and national security are the main factors influencing a country’s nuclear program decisions.
- Leaders consider pressures from political ambitions, interest groups, and national prestige.
- Security concerns, especially threats from neighboring countries, can drive nuclear development.
South African Nuclear Ambitions
- In the late 1960s, South Africa began its nuclear program for infrastructure, driven by influential economic sectors.
- The National Party’s apartheid policies made South Africa an international pariah, compounding isolation.
- South Africa did not sign the Nuclear Nonproliferation Treaty (NPT) in 1968, increasing international isolation.
- Despite sanctions and sporting bans, leaders believed nuclear weapons would provide security, not further isolation.
- Post-1975 independence of neighbors like Mozambique and Angola raised fears of communist encirclement, motivating nuclear armament.
Reasons for Giving Up Nuclear Weapons
- In 1991, South Africa dismantled its nuclear facilities and later joined the NPT as a nonnuclear state.
- President F. W. de Klerk initiated disarmament due to fears that the opposition African National Congress (ANC) might control nuclear arms.
- International reintegration, lifting of sanctions, and participation in global events motivated denuclearization.
- Regional threats diminished after the Cold War and end of conflicts, reducing the perceived need for nuclear weapons.
Lessons from the South African Case
- Nuclear decisions are shaped by both domestic and international pressures and changing security environments.
- Case studies like South Africa’s help understand factors that drive nuclear acquisition or disarmament.
