Several years ago, as the primary focus of U.S. military strategy shifted to the western Pacific region, many respected authorities began to question the relevance of the North Atlantic Treaty Organization (NATO) in modern world events. More recent events, such as the Russian Federation's annexation of Crimea, have given policy makers pause to question the wisdom of anticipated force cuts in Europe. Amidst this turmoil, the staffs of U.S. European Command and U.S. Army Europe have been establishing and refining their capabilities to conduct military operations in and through the cyberspace realm. If indeed the decision is made to pursue military action in cyberspace, what capabilities are available within NATO forces to accomplish such activities? What organization, doctrine, and methods would guide operators who perform such actions? In this monograph, Mr. Jeffrey Caton explores these questions within the broader context of the continued evolution of the NATO Alliance.
