Denmark has presented since the Cold War one of the most unique foreign, security and defense policy among the European nations. Its unique position allows us to understand the difficulties surrounding existing security flows in Europe. With the end of the Cold War, it was possible to note the emergence of new threats to security and stability of the European countries which turned out to influence the Danish political relations to international organizations responsible for ensuring the country's security, both within Nordic range (Nordic Council), as in European (EU) and Atlantic (NATO) scope. Therefore, this study aims to analyze the changes in the Danish policies in relation to these international organizations after the 'rise' of these new security challenges, arguing that the position 'or Nordic, or EU, or NATO', common in Cold War, had been converted into a 'Nordic, EU and NATO' position.
