The demand follows Monyela’s interaction on social media where he appeared to endorse the suggestion that South Africa should revive its nuclear weapons programme to act as a deterrent against the United States.A "Flippant" Endorsement with Serious ConsequencesIn a statement released immediately on Sunday, DA National Spokesperson Jan de Villiers MP described the incident as an "extraordinary and deeply irresponsible statement."The controversy stems from a public exchange in which Monyela reportedly responded approvingly to a user suggesting South Africa requires nuclear capability to counterbalance American influence. While the DA acknowledged the comment may have been "flippant," De Villiers argued that senior diplomats do not have the luxury of off-the-cuff commentary on matters of existential security."Officials like Mr. Monyela cannot unilaterally make wide-reaching policy pronouncements on behalf of the GNU," said De Villiers. "The DA is firmly of the view that him or DIRCO endorsing nuclear proliferation directly contradicts South Africa’s commitments under the Nuclear Non-Proliferation Treaty."The Context: Digital Diplomacy and Anti-Western SentimentTo long-time observers of South African diplomacy, the incident highlights a recurring friction. Monyela, a veteran communicator, has often used social media to defend Pretoria’s foreign policy aggressively. His style appeals to a domestic constituency that views the West with suspicion, but it frequently risks blurring the lines between personal opinion and official state policy.The context of the "nuclear" comment is likely rooted in the growing assertiveness of the Global South and the BRICS bloc, where there is simmering resentment regarding perceived American hegemony. However, for a South African official to flirt with nuclear proliferation is particularly sensitive. South Africa remains the only country in history to have voluntarily developed and then dismantled a nuclear arsenal—a legacy that anchors its moral authority in global disarmament forums."It is hugely ironic for DIRCO to invoke international law to criticise great-power behaviour while simultaneously having its senior officials endorsing the most catastrophic instruments of force ever devised," De Villiers noted.The GNU Friction PointThe clash underscores the ideological divergence between the ANC, which controls DIRCO, and the DA, its partner in the GNU. The DA views the United States as a vital economic partner, prioritising trade stability and the African Growth and Opportunity Act (AGOA). In contrast, elements within the ANC and DIRCO often prioritise solidarity with anti-imperialist movements, sometimes at the cost of diplomatic niceties with Washington.De Villiers emphasized the economic stakes: "DIRCO should be working actively to stabilise and normalise relations with the United States, one of our largest trading partners and key source of foreign investment and job creation. In the current climate, Mr. Monyela’s provocative and irresponsible statement is especially damaging."Demands for AccountabilityThe DA has called on International Relations Minister Ronald Lamola to publicly distance the department from Monyela’s remarks. Furthermore, they have requested that DIRCO Director-General Zane Dangor institute disciplinary steps and that Monyela issue an "unambiguous public apology."The incident serves as a reminder that while the GNU has signed a Statement of Intent regarding a "non-aligned" foreign policy, the interpretation of that term remains a battleground. For the DA, non-alignment means balanced engagement; for some in DIRCO, it often implies a reflex to challenge Western power."Public diplomacy exists to reduce tensions, not inflame them," De Villiers concluded. "Reckless signalling that suggests hostility is therefore out of line."As of Sunday afternoon, DIRCO had yet to issue an official response to the DA’s demand.
