There is no doubt that the Soviet occupation of Afghanistan is a crisis, and a different sort of crisis than the kind we have been accustomed to over the years of the cold war and the period that came to be known as detente.

The Berlin crises were serious and worrisome, but they came and went and some degree of normality was restored.
