For reasons that are now generally familiar, the United States is obliged to assign a very high priority to the defense of industrial western Europe in shaping its global strategy. But it remains a fact that the area of continuing tension in world affairs is much more extended. Broadly speaking, one can trace this area of tension in a great semi-circle from the North Cape of Norway down through central Europe and the Balkans, across the Middle East, through Southeast Asia, and then northward again to Korea. This is the perimeter of the Soviet world, minus its Arctic frontier. If we snip off the European segment of the arc, as constituting a problem apart, what we have left is the southern and eastern perimeter of Asia, fronting the Pacific and Indian Oceans.
