The 'realist' conception of continuing old-fashioned 'balance of power' politics may have been well founded in the past, but it is inconsistent with our increasing interdependent world. On moral grounds alone there can be no justification for the 20th century level of killing. To settle disputes without violence must become the primary goal of foreign policy for every nation.
Robert McNamaraI would characterize current US nuclear weapons policy as immoral, illegal, militarily unnecessary, and dreadfully dangerous
Robert McNamara...but highly placed sources within the Kennedy Administration disagreed: "[T]he assumption that the strategic nuclear balance mattered in any way was wrong... As far as I am concerned, it made no difference... If my memory serves me correctly, we had some five thousand strategic nuclear warheads as against t heir three hundred. Can anyone seriously tell me that their having three hundred and forty would have made any difference? The military balance wasn't changed. I didn't believe it then, and I don't believe it now..."
