The only thing that kept the Cold War cold was the mutual deterrence afforded by nuclear weapons.

The lesson of the Cold War is that against nuclear weapons, only nuclear weapons can hold the peace.

If ever there was an unnecessary weapon after the Cold War, it's nuclear weapons. We have nuclear capability to burn. This is a situation where the broader policy issues are more important than the job loss.

We have got thousands of nuclear weapons in order to achieve deterrence.

The politicians always told us that the Cold War stand-off could only change by way of nuclear war. None of them believed that such systemic change was possible.

The South Africans decided that they would like to prove to the world they did not have any nuclear weapons and their decision was not doubted because it was the end of the Cold War, it was also the end of apartheid.
