As one attempts to think through the implications of the Cuban crisis for Berlin, it seems especially important not to generalize without careful analysis of all the factors in the two situations. It is understandable that in our first elation at “victory” the advocates of a hard line with Russia should assume that a similar, policy wilt work in Berlin. Actually, one must recognize that the blockade which obtained the withdrawal was a graduated use of force directed at a limited objective. It is by no means clear that a different procedure, for example carrying our grievance to the United Nations, would not have worked as well or better, particularly if one of our policy aims is to strengthen the United Nations.
