The article deals with the problem of the impact of transatlantic relations on the shape of internal security of the European Union especially in the context of escalation of unconventional threats. It also shows the dependence between the ability to co-shape the international framework of security and the maintenance of a strong position on the international arena together with possibilities of an unhampered development. At the threshold of the 21st century issues of EU’s internal security were strongly correlated with broadly understood international security. This is particularly visible in transatlantic relations with growing expectations towards the EU to play the role of USA’s partner and to take upon itself responsibility for its own security to a larger extent than before.
