摘要:Volumen III - 2003 ISSN 1870-4654 INTERNATIONAL LAW AND THE ANGRY SUPERPOWER * Michael BYERS ** Widespread sympathy in the aftermath of 11 September and heightened concern about terrorism have made possible for the US the securing of a long-sought-after goal: an extension of the right of self-defence, a right well established in customary international law, to include military responses against States that support or harbour terrorist groups. Having reached that goal, the US may now try to develop a right of anticipatory self-defence. It is possible too, the author holds, that instead of seeking change in the existing rules, the US is in fact attempting to create new, exceptional rules for itself alone. The success in the changing of customary international rules as well as the development of exceptional rules, the author warns us, would depend on the responses of other countries to such actions . * Ponencia presentada en el seminario internacional "El derecho internacional". ** Associate Professor, Duke University School of Law; Peter North Visiting Fellow, Centre for Socio-Legal Studies & Keble College, Oxford University. * Nota: Debido que la traducción es automática podrá ser inexacta o contener errores.
