The Fallacy of Unambiguous Warning

The Indications and Warnings subfield of intelligence has traditionally divided warnings into a dichotomy of "ambiguous" and "unambiguous" that gives policymakers a false sense of security. This article examines how unambiguous warning has been conceptualized and why it has become an inadequate planning tool that can lead to dire consequences in the quest for certainty. Using the 1973 Yom Kippur War and the Pearl Harbor attack as case studies, the article shows unambiguous warning is an inadequate planning tool that can lead to dire consequences in the quest for certainty. The article concludes with observations about the role of intelligence and the future of military planning.
