Abstract
It has been said about the United States that it is now suffering ‘a crisis of regime’. Europe, we have been told, is in little better condition: ‘all over Europe the First World War broke up the structure of society which, before 1914, had provided the necessary basis of confidence between government and governed. There no longer exists, except in a few places such as Switzerland, that general acceptance of the conduct of national affairs that adds to the vigor of government and society alike.’1These are the kinds of practical political problems to which the concept of political support, as found in systems analysis, has been directed.
