What are the chances that international society will be able to respond positively to the second chance identified by the United Nations Secretary-General? The scale of UN activity since the end of the Cold War might be offered as evidence that we are entering an era when international obligations will at last rank alongside the defence of national interests, even if they will not necessarily take precedence over them. Of the twenty-nine ‘peacekeeping’ operations established by the UN since 1945, sixteen have been created since 1987. At the same time, few of these operations have been unqualified successes, and the demands placed on the UN system can equally be interpreted as evidence of spreading chaos and widespread threats to stability and international order in the wake of the collapse of familiar Cold War structures. Moreover, the potential demand for UN intervention around the world is clearly greater than the Organisation's ability to respond, given the resources currently available to it, or which seem likely to be made available in the foreseeable future. Indeed, by the end of 1993 there were clear signs that the governments of the major powers were more interested in limiting than extending their international commitments.
