In the European security calculus, terrorism has become one of the key strategic threats. Alarmingly, the continent has also become a centre of radical Islamist propaganda and activism, with a number of European countries worried over the potential of their own 'home-grown' religious extremists. Latest studies indicate a disturbing trend of a section of the youth, generally belonging to the Muslim communities of West African and South Asian origin from a poor or middle class socioeconomic background, embracing extremism and terrorism in Europe.

During the latest war in Iraq, which has now come to an end, there has been a persistent debate on why Europe and the US are not seeing eye-to-eye on the question of war and a host of issues pertaining to it. The discourse so far has speculatively tried to probe whether the whole mismatch is about culture, history or about the power game in the post-Cold War world.

The post-Cold War period saw North Atlantic Treaty Organisation (NATO) being expanded not once but twice. In foreseeing the security threats of the 21st century, NATO is seeking to recast its strategic response. The EU and the US are united in their opinion about the need for a stronger and cohesive NATO, and a wider out-of-area role for the alliance. If both the sides start working together and address future challenges, it may bring about a ‘symbiosis’ in the Atlantic Relationship.

Significant changes have been witnessed in major centres of military production in recent times. Since the end of the Cold War, indicators of military production – expenditure, R&D expenditure, demand and supply of weaponry, and others – have shown fluctuations. Military efforts of States decelerated for nearly a decade, only to rise again since the late 1990s.
