There was an expectation that the end of the Cold War would herald a new era of peace and stability in which the importance of nuclear weapons was marginalized. Instead, we have been left with a fractious, inter-dependent international community rife with ethnic and religious tension and unbound by super-power competition. The challenges of climate change, demographic shifts and resource competition have further altered the security environment. As if this were not enough, nuclear proliferation is once again at the top of the international agenda.
In the last decade the Nuclear Proliferation Treaty (NPT) has been challenged from within by Iraq, Iran and Libya while Indias, Pakistans and North Korea's nuclear weapon capabilities are threatening the non-proliferation norm from without. The new proliferators are predominantly, but not exclusively, aggressive, unstable and authoritarian regimes, considered by many in the international community to be outside the constraints of international normative behaviour. Some have even been labelled `outlaw, or `rogue states. Although inter-continental nuclear war is not presently considered a danger, the increased number of nuclear weapons states combined with the nature of those states and the strategic environment in which they exist makes the possibility of a lesser nuclear exchange potentially much greater. In parallel, the 9/11 atrocities raised fears of the prospect of apocalyptic terrorists acquiring nuclear weapons. Indications that the NPT is failing to rise to the challenge have resulted in policy decisions that have arguably reversed both the disarmament and non-proliferation norms.
This volume delves deep into the changing global nuclear landscape. The chapters document the increasing complexity of the global nuclear proliferation dynamic and the inability of the international community to come tol³4
