The United states and its Western European allies are the hegemonic world powers, and the architects of the global order we live in. From military power and the institutional make-up of the global economy, to political, diplomatic and cultural influence the Western alliance is beyond comparison to its smaller regional rivals. But this alliance is under greater pressure than anytime since the cold war. Global dynamics including deglobalisation and the emergence of regional powers including China, Russia and India are testing its strength. Popular movements are corroding the authority of institutions like the EU and financial centres. This decline produces both dangers and opportunities for new foreign policy alternatives to Western global dominance.
