I appreciate what the hon. Gentleman is saying, and he is being very reasonable in his approach. The point about the second centre of decision making, which both Republican and Democrat American Governments have supported since 1958, is about the danger that another country might think it could pick off the UK without the Americans responding on our behalf. They probably would respond but it would be too late by the time the aggressor found that out. That is why knowing that the UK can defend itself is welcomed by the Americans, so that no fatal miscalculation of that sort can be made.
