It is clear then that the Non Proliferation Treaty has enjoyed some success in curbing nuclear proliferation; most states have signed and abide by the rules of the NPT. The example of the A.Q Khan network as a non-state actor taking an active role in proliferation is a classic example of how the NPT is not effective at dealing with the problems the post cold war world faces.

What has begun as the “War on Terror” and is now a series of “overseas contingency operations” could in fact only go on in the global fashion that it did for almost ten years now because of the services provided by several hundred thousand contractors. In short, private contractors serve as enablers of this decade-old war, much like they have become enablers of most major Western militaries.

Realism leaves little place in order to study broader fields such as health security that states may face, and therefore does not take into account HIV/AIDS as a threat to human, national or international security. However, scholars have recently emphasised the growing negative effects of HIV/AIDS on core pillars of states, receiving ever more attention by policy-makers as a potential threat to national security.

The notion of popular sovereignty stands in contrast with Iran’s religious lineage. This dichotomy makes it difficult for the state to materialize its diplomatic goals, which only isolates it from the international system, fueling the need to expand its nuclear program in an effort to ensure national security. It is virtually impossible for Iran to forge successful international relations when it suffers from the national clashing principles of Islamic rule and popular sovereignty.

The Realist emphasis on military strength does not conclusively explain world politics. For a school of thought focusing on power, Realism misunderstands what it means to ‘have power’. The failure of Israel to gain security demonstrates the contextual and contingent nature of power, and how military capacity is not the means to all ends.
