The arguments over nuclear policy between the United States and her allies were often as acrimonious as those between the Soviet Union and China, but they did not result in such a stark deterioration in political relations. France disentangled herself from NATO but the break did not turn out to be as complete as at first seemed likely. Furthermore, one result of the French withdrawal was to make possible a compromise position within NATO in which Europeans endorsed the formal US position while making it clear that they would not devote great resources to implementing it. The strategy of flexible response was adopted by NATO in 1967:
This concept … is based upon a flexible and balanced range of appropriate responses, conventional and nuclear, to all levels of aggression or threats of aggression. These responses, subject to appropriate political control, are designed, first to deter aggression and thus preserve peace; but, should aggression unhappily occur, to maintain the security of the North Atlantic Treaty area within the concept of forward defence.
