Overview of the Current Problem Realization of national interests is the concern of many states in the current international and security is the main challenge that each government is trying to cope up with given the fact terrorists are ever devising new ways of intimidating state actors globally. Realists are of the view that no state will ever be interested in benefiting another actor in the global system meaning the focus is always on designing the best policies that will be helpful in goal achievement. Based on this, the state has to deal with all conditions that might interfere with security to an extent that it might choose to intervene militarily in another sovereignty state to flush out bad elements that are considered a major impediment towards attainment of objectives. In 2003, the US embarked on an extensive program in the Middle East aimed at dealing with the members of the Al-Qaeda group after the bombing of the twin towers. Subsequently, the US has ensured that the belligerent actors and rogue states are prevented from committing the worst crimes, such as killing the innocent people. This has not been an easy task since the government has been forced to establish an entire department referred to as the homeland security whose major mandate is to prevent the occurrence of terrorism in the state borders. In the current international system, each actor is focused on promoting his or her interest implying the system is comparable to the Hobbestian state of nature where life was nasty, brutal, short-lived, and anarchic. In the state of nature as expressed by Hobbes, human beings realized the need for coming together to end the poor conditions when they agreed to form a leviathan, which was equivalent to the modern day government. Each person was expected to surrender his or her sovereignty to the common authority referred to as the leviathan. The universal authority was given adequate powers to act unilaterally, but through consultation with other members of the public. In the state of nature, the leviathan ensured no person threatened the existence of others by developing laws that were inclusive. In the modern global system, states are reluctant to surrender their sovereignty to the common authority the way individuals decided to hand the Leviathan with adequate powers. The UN is a representative of the leviathan because it is charged with the mandate of formulating and designing policies that guide the conduct of both state and non-state actors globally. For instance, the UN Security Council has been vocal since early 1990s, especially in dealing with rogue states that are indifferent to the demands of their people. It slapped economic sanctions to the government of Libya, which forced the state to comply with the international law. In the ongoing Arab Spring, the Security Council has done some commendable job by imposing a no-fly-zone rule to force the dictators to surrender. Various agencies controlled by the UN have been working hard to champion for the policies that are meant to improve the living standards of global citizens. However, the UN has been unable to marshal states to surrender their sovereignty, as far as maintenance of security is concerned. This has forced several states to spend heavily on defense and policing.
