Transatlantic cooperation,alliance politics and extended deterrence: European perceptions of nuclear weapons

This article discusses the North Atlantic Treaty Organization (NATO) debate regarding American nonstrategic nuclear weapons (NSNW) in Europe, given the broad spectrum of views on nuclear issues when comparing individual member states. What is striking is the gap between public attitudes – which are broadly hostile to keeping NSNW in Europe – and elite opinion, which privileges the maintenance of NATO commitments to preserve alliance cohesion. To better understand this tension, this article dissects the elements of extended nuclear deterrence in Europe, addressing the difficulties associated with current nuclear-sharing arrangements. For some NATO states, the alliance's nuclear weapons are a political liability, since nuclear sharing clashes with international disarmament and nonproliferation commitments. For other NATO members, maintaining the status quo is preferable, as long as there is no alliance-wide consensus on the question of NSNW. These debates have been put to rest, for now, with NATO's Deterrence and Defense Posture Review, which reaffirmed the purpose of the alliance's nuclear weapons. However, these divisive debates point to more fundamental issues in alliance management, namely the credibility of American commitments, the sustainability of extended nuclear deterrence in Europe and the inevitable political tensions these questions provoke at the domestic level for NATO allies.
