(Disclaimer: From a pinko's anti-nuke perspective)*
With the current debate on Trident, there are two audio clips that are worth listening to. One, from the Now Show, is funny and new and borrows from the other, which is a speech called 'Nuclear Weapons are Morally Indefensible' and is from the late New Zealand Prime Minister, the Hon David Lange. This is old and occasionally funny, was the Oxford Union Debate in 1985, and while being quite long is worth listening to. It remains as prescient today as it did in 1985.
By the way, Aotearoa is still being punished by our 'friends' for this one.
