I have to share this beautiful moment in New Zealand's history ... I wanted to put it someplace so I can go back to it sometimes.
We were so proud of him, that country of mine.
Anyway, let me quote wikipedia, to get the story right: David Lange was the 32nd Prime Minister of New Zealand from 1984 to 1989. He headed New Zealand's fourth Labour Government, one of the most reforming administrations in his country's history, but one which did not always conform to traditional expectations of a social-democrat party.
He had a reputation for cutting wit (sometimes directed against himself) and eloquence. His government implemented far-reaching free-market reforms. Helen Clark has described New Zealand's nuclear-free legislation as his legacy.
Lange made his name on the international stage with a long-running campaign against nuclear weapons. His government refused to allow nuclear-armed ships into New Zealand waters, a policy that New Zealand continues to this day. The policy, developing in 1985, had the effect of prohibiting United States Navy ships from visiting New Zealand.
This displeased the United States and Australia: they regarded the policy as a breach of treaty obligations under ANZUS and as an abrogation of responsibility in the context of the Cold War against the Soviet bloc. After consultations with Australia and after negotiations with New Zealand broke down, the United States announced that it would suspend its treaty obligations to New Zealand until the re-admission of United States Navy ships to New Zealand ports, characterising New Zealand as "a friend, but not an ally".
Erroneous claims sometimes suggest that David Lange withdrew New Zealand from ANZUS. His government's policy may have prompted the US's decision to suspend its ANZUS Treaty obligations to New Zealand, but that decision rested with the U.S. government, not with the New Zealand government.
The Oxford Union debate shown below, went out live on New Zealand television in March 1985 showcased Lange, a skilled orator, arguing for the proposition that "nuclear weapons are morally indefensible", in opposition to U.S. televangelist Jerry Falwell. Lange regarded his appearance at the Oxford Union as the highest point of his career in politics.
