The rise of new Great Powers, namely the ‘BRICs’ and the return of multipolarity at the global level in turn carries security implications for western Europe.

While peaceful political relations within the European Union have attained a remarkable level of strategic, institutional and normative embeddedness, there are five factors associated with a return of Great Power competition in the wider world that may negatively impact on the western European strategic environment: the resurgence of an increasingly belligerent Russia; the erosion of the US military commitment to Europe; the risk of international military crises with the potential to embroil European states; the elevated incentive for states to acquire nuclear weapons; and the vulnerability of economically vital European sea lines and supply chains.

These five factors must, in turn, be reflected in European states’ strategic behaviour. In particular, for the United Kingdom—one of western Europe's two principal military powers, and its only insular (offshore) power—the return of Great Power competition at the global level suggests that a return to offshore balancing would be a more appropriate choice than an ongoing commitment to direct military interventions of the kind that have characterized post-2001 British strategy.
