摘要：The appearance of the nuclear weapons at the end of the Second World War, as well as their development in an extremely high number (of the order of tens of thousands) by the great powers, especially during the Cold War, represented first of all a real problem of security for the humanity. The present paper aims to evaluate both aspects regarding the alarming nuclear race, especially after the '50s, but mainly the way in which it has been attempted over the last decades to stop/diminish the development of the nuclear arsenal at a global level with extremely high direct/potential destructive effects for human and the environment. Although in the last 5 decades there have been numerous strategies of abolition/non-proliferation of the nuclear arsenal, part of these being briefly presented in this paper, the real decrease of the nuclear weapons strength has proved to be extremely difficult, especially in the context in which their existence has represented until now one of the most important guarantees for the preservation of the geopolitical and geostrategic supremacy of the great powers.
