The decline of inter-state war does not mean that the world has become a safer place. Rather, new and, in some ways, more challenging, security threats have emerged. This particularly applies in the case of terrorism, as demonstrated by 9/11 and other attacks. Terrorism, indeed, shows how globalization has made the world more dangerous, as terrorists gain easier access to devastating weaponry, and can operate on a transnational or even global basis. Such threats underline the need for states to develop more sophisticated military strategies, both to ensure tighter domestic security and, possibly, to attack foreign terrorist camps and maybe states that harbour terrorists.
