Turkish Foreign Minister Hakan Fidan has warned that Iran's acquisition of nuclear weapons could trigger a regional arms race, reshaping security dynamics and pressuring neighboring countries to reconsider their own nuclear options. Fidan emphasized Turkey's opposition to nuclear proliferation and called for renewed diplomacy, stressing that preventing Iran from obtaining nuclear weapons should be a shared international priority. He cautioned that once proliferation pressures begin, reversing them becomes much more difficult, and the emergence of new nuclear powers would heighten risks of escalation and miscalculation.

Fidan also dismissed the likelihood of regime collapse in Iran following potential airstrikes, arguing that such actions would not bring about significant change and could instead provoke more radical decisions from the Iranian government. He reiterated that Turkey prefers de-escalation and diplomatic solutions to avoid a possible war and affirmed that there is currently no immediate threat of conflict.

Additionally, Fidan stated that Iran does not possess atomic bombs and claimed there is no evidence that Tehran intends to build them, citing a religious decree by Iran's Supreme Leader forbidding nuclear weapons. He noted that while Iran develops capabilities close to weaponization, it faces sanctions and international scrutiny, but as long as it does not cause global problems, there are few complaints about its regime.
