This paper addresses threats to international security this problem. Hopefully it will initiate terrorist acquisition and possible use of scholarly discussion and analysis. nuclear explosive devices, radiological weapons, or attacks on various nuclear Defming Nuclear Terrorism. Nuclear facilities and installations.3 Few studies terrorism can be defined as the have examined the problems arising unauthorized use or .attempted use of from incidents of nuclear terrorism, nuclear explosive devices, use or choosing instead to focus solely on the attempted use of nuclear materials, or feasibility or probability of nuclear ter attacks or attempted attacks on nuclear rorism. These studies have resulted in facilities and installations for ex significant improvements in efforts to tortionate purposes. The victim of 533 nuclear terrorism may be an individual, to fabricate natural uranium isotope a group of individuals, an organization, 238 into a nuclear explosive device. or a government. The primary actor on It is important to bear in mind that a whom the burden of response to nuclear terrorist trying to construct a nuclear terrorism will fall, however, is the gov explosive device does not operate under ernment of a nation on whose territory the same rigorous performance con nuclear terrorist acts are committed. straints that bound the efforts of a Governments rather than individuals, military weapon designer.
