The formulation of foreign policy is at best an inchoate process. The very term implies an orthodoxy of identification, pursuit and maintenance of perceived interests which is often patently lacking in reality. When a nation is beset by a declining capacity to exert influence in a particular region as a result both of competition from other powers and of incipient assertiveness on the part of local interests, the foreign-policy process may be reduced to one of administering ad hoc responses to particular developments which appear to lack any overall rationale.
