On 25 October 1962, during a tense UN Security Council meeting amidst the Cuban Missile Crisis, US Ambassador Adlai Stevenson delivered a powerful ultimatum to Soviet representative Valerian Zorin.
As the world teetered on the brink of nuclear war, Stevenson demanded Zorin confirm or deny the presence of Soviet missile bases in Cuba.
When Zorin attempted to deflect the question, Stevenson, with an unyielding resolve, famously declared, "I am prepared to wait for my answer until hell freezes over." His bold confrontation became a defining moment of Cold War diplomacy, reflecting the intensity and high stakes of the crisis.
