LOPES, Dawisson Belém and CASAROES, Guilherme Stolle Paixão e. UN and collective security in the 21st century: tensions between political authority and the effective exercise of coercitive power. Contexto int. [online]. 2009, vol.31, n.1, pp. 9-48. ISSN 0102-8529. http://dx.doi.org/10.1590/S0102-85292009000100001.
This essay argues it is plausible to attribute to the United Nations organization the condition of important locus of political authority in contemporary international relations, despite its flagrant difficulty in enforcing, by means of organized violence, significant parcel of its determinations - especially those related to collective security issues. We hereby offer a new account of the institutional crisis brought about by Anglo-American invasion of Iraq in 2003.
