If Paris is the third centre, let us have the fourth centre somewhere else. Then, presumably, we can sleep more soundly in our beds.

The idea of creating uncertainty and of a second centre of decision making is ludicrous. If a nuclear war were to break out, that would be likely to happen at a time of grave international tension, similar to what happened in the Cuban crisis a few years ago, when one side, out of fear, error, and uncertain information, panics and is tempted to go for a first strike. In such a situation a second centre of decision-making creating uncertainty merely increases misunderstanding and encourages misapprehension and panic. Therefore, I hope that the Government will drop the notion that somehow they can defend their independent nuclear deterrent by those specious arguments.
