Nuclear terrorism, according to a 2011 report published by the Belfer Center for Science and International Affairs at Harvard University, can be executed and distinguished via four pathways: The use of a nuclear weapon that has been stolen or purchased on the black market The use of a crude explosive device built by terrorists or by nuclear scientists who the terrorist organization has furtively recruited The use of an explosive device constructed by terrorists and their accomplices using their own fissile material The acquisition of fissile material from a nation-state.
