Lottaz, Iwama, and their contributors investigate the role of neutral and nonaligned European states during the negotiations for the Treaty on the Nonproliferation of Nuclear Weapons (NPT). Focusing on the years from the Irish Resolution of 1958 until the treaty's opening for signatures ten years later, the nine chapters written by area experts highlight the processes and reasons for the political and diplomatic actions the neutrals took, and how those impacted the multilateral treaty negotiations.
