South Africa has stepped into a defining diplomatic moment. Speaking at the United Nations Disarmament Conference, Minister of International Relations and Cooperation Ronald Lamola declared that nuclear weapons have "no place in the 21st century," as Pretoria prepares to chair the upcoming review of the Treaty on the Prohibition of Nuclear Weapons (TPNW).
Addressing delegates at the United Nations, Lamola framed South Africa’s upcoming role not as ceremonial, but as consequential. In a world unsettled by geopolitical rivalry, renewed arms spending and open conflict, he argued that the continued existence of nuclear weapons represents a failure of global political imagination.
"There is no place for nuclear weapons in the 21st century," Lamola said, calling on states to recommit to multilateral solutions and international law.
A Country With Moral Authority on Disarmament
South Africa occupies a rare position in nuclear history. It remains the only country to have voluntarily dismantled its nuclear weapons programme and joined the global non-proliferation regime as a non-nuclear-weapon state. That decision in the early 1990s reshaped its diplomatic identity and continues to underpin its credibility in disarmament forums.
By chairing the TPNW review conference, Pretoria is expected to steer discussions on compliance, verification, victim assistance and universalisation of the treaty. The role places it at the intersection of competing worldviews: nuclear-armed states that resist the treaty and non-nuclear nations that see it as a moral and legal imperative.
Why the Treaty Matters Now
The Treaty on the Prohibition of Nuclear Weapons, which entered into force in 2021, outlaws the development, testing, possession and threat of use of nuclear arms among its signatories. However, its influence remains constrained by the absence of nuclear-armed states among its members.
Lamola’s remarks come at a time when nuclear rhetoric has resurfaced in global conflicts and strategic alliances are hardening. For many Global South nations, frustration is growing as progress under older disarmament frameworks stalls while modernization of nuclear arsenals continues.
Leadership Beyond Symbolism
South Africa’s chairmanship will test whether moral clarity can translate into diplomatic momentum. The review conference is expected to focus on practical pathways — from encouraging broader ratification to strengthening humanitarian arguments around the catastrophic consequences of nuclear use.
- Expanding treaty membership among non-signatory states
- Reinforcing international norms against nuclear threats
- Centering humanitarian and environmental consequences
- Encouraging dialogue between nuclear and non-nuclear states
For Pretoria, the moment carries strategic weight. It reinforces South Africa’s longstanding commitment to multilateralism while elevating its profile as a bridge-builder between developed and developing nations.
Whether the upcoming review conference produces measurable breakthroughs remains uncertain. Yet Lamola’s message was unmistakable: disarmament is not a relic of Cold War diplomacy, but a contemporary necessity.
As global tensions persist, South Africa’s leadership will be closely watched. The question is no longer whether the world understands the danger of nuclear weapons — but whether political will can finally catch up with that understanding.
