"The demise of the Soviet Union and Warsaw Pact left the United States with no single identifiable threat. The 'victory' of the Cold War has not provided the US with a significant 'peace dividend' as predicted, but instead presents an unstable and uncertain world. Future conflicts may present US forces with enemies which do not represent traditional nation-states but are instead formed from ethnic, religious, tribal, criminal, or corporate based groups. The current intelligence preparation of the battlefield (IPB) process provides a useful framework for organizing information required by future commanders. What is lacking, however, is an appreciation for all of the intangible factors which may influence that battlefield based on the potential disparity of actors involved."
