“We have more nuclear warheads than the Russians, and I consider this to be the most important measure of relative strength. In addition, as Dr. Kissinger stressed many years ago, at the present level of strategic armaments superiority in numbers or megatons has no meaning.”

“The most interesting thing I learned during this time was how small a nuclear warhead was.”
On his experiences in the military during his training on how to fire Pershing missiles.
Nobel Prize autobiography (1998)
Context: Oklahoma is laid back and rather beautiful, with rolling brown hills not unlike the ones in California. The Pershing missiles, on the other hand, were not beautiful. They were horrible weapons of war — solid-fuel rockets five feet in diameter at the base, long as a moving van, and capable of throwing a tactical nuclear warhead 500 miles. They were launched from trucks and required a team of 10 men to service and fire. The most interesting thing I learned during this time was how small a nuclear warhead was. The nose cone of a Pershing is only about 18 inches in diameter at the base. I had not been interested at all in nuclear weaponry as a student, and so I had never thought through carefully about their "efficiency". It is sobering thought that these missiles were actually deployed in continental Europe in those days and that on at least one occasion, namely the 1973 Arab-Israel war, there was an alert serious enough to leave the commanding officers trembling.

“We still have 27,000 warheads in existence. I believe this is 27,000 too many.”
Nobel lecture (2005)
Context: Are these goals realistic and within reach? I do believe they are. But then three steps are urgently required.
First, keep nuclear and radiological material out of the hands of extremist groups. … we are in a race against time.
Second, tighten control over the operations for producing the nuclear material that could be used in weapons. Under the current system, any country has the right to master these operations for civilian uses. But in doing so, it also masters the most difficult steps in making a nuclear bomb.
To overcome this, I am hoping that we can make these operations multinational — so that no one country can have exclusive control over any such operation....
Third, accelerate disarmament efforts. We still have eight or nine countries who possess nuclear weapons. We still have 27,000 warheads in existence. I believe this is 27,000 too many.
