International law clearly requires an imminent threat of attack as a justification for the preemptive use of military force. However, the standard definition of an imminent threat was derived centuries before the development of nuclear, chemical, or biological weapons or ballistic missiles and other delivery systems that can reach their targets in a matter of minutes. Any use of force to alleviate threats posed by weapons of mass destruction (WMD) prior to tactical warning of the actual launch of such weapons falls into the legally and ethically controversial category of “anticipatory self-defense,” leaving decision makers potentially liable to prosecution for war crimes. Effective and ethical enforcement of nonproliferation therefore demands a standard for imminence of threat broad enough to allow military action as a last resort but sufficiently restrictive to prohibit indiscriminate action against suspected WMD programs. Following a critical review of selected literature and cases on preemption, the author proposes a new standard for preemptive military action: the existence of operational WMD, or a clandestine program to develop WMD, in contravention of international law. The author discusses the implications of this new proposed standard, which at the time of writing would permit preemptive attack against WMD-armed terrorist groups but prohibit it against all states except Iran and possibly North Korea. 相似文献

This essay explores the obligations arising from the United Nations Convention against Transnational Organised Crime, signed in Palermo, Italy at the end of 2000. It also discusses the initiatives required to prepare the legal system and related infrastructure of Zimbabwe for its implementation. Zimbabwe joined more than 120 other countries in signing the Palermo convention, but has not yet ratified it. The ratification would enshrine the latest initiatives to develop effective strategies against transnational organised crime. The Palermo convention makes demands on the laws and institutions of states parties which could enhance their capacity to confront organised crime. Ratification signifies competence to implement the prescribed obligations, which can only occur after introducing suitable domestic laws, and adopting the necessary administrative mechanisms. The required reforms are bound to have certain policy and legislative implications for Zimbabwe. Regional initiatives complementary to the Palermo convention are expected to catalyse positive changes in Zimbabwe's response mechanisms. 相似文献

Bribery undermines human development and a transition to stable democratic rule. It props up illegitimate regimes as corporations bid for contracts by bribing, in a seeming race to the bottom. The world's wealthy are slowly waking up to this and criminalising this scandalous practice of bribing foreign public officials. However, such measures, if enforced, need to be combined with domestic anti-corruption strategies in the South. If this opportunity is missed, the risk of investing private capital in marginalised economies perceived to be highly corrupt is further upped, making investment-driven economic growth possibly even less unattainable. 相似文献
