Terrorism In the current international system, terrorism is the major threat facing all actors, including the United Nations. Countries are faced with both internal and external threats, but terrorism remains the major threat. Terrorism is a problem that cannot be solved unless United Nations delves into its origins. Terrorists use violence to frustrate governments in the world, irrespective of whether the country is developed or poor. In other words, no country or individual is spared by the heinous acts of terrorists. States have been forced to cooperate in order to combat terrorism. In the modern international system, there are various categories of terrorists, each with its own mode of operation. Some of the terrorists posses weapons of mass destruction while others resort to suicide bombing. Scholars argue that terrorism is a result of depression, melancholy, hopelessness, helplessness, and defeat. Before the Cold War era, terrorism was not a big issue in the international system because Islam was under control of the US and the Soviet Union (Sasley 2011, p. 21). The hostilities between the US and the Soviet Union did not give room to terrorism. The United Nations faces a big challenge as regards to terrorism. Weapons and Mass Destruction Production of weapons and availability of weapons of mass destruction is another threat to world security in the current international system. It is upon this that the Atomic Agency was created to supervise the production and distribution of weapons of mass destruction. Before the Cold War, only powerful states, such as Russia and the US, had the capability of producing weapons of mass destruction. In this regard, the weapons could not be used to destroy life and property. In fact, the superpowers wanted to prove to each other that they were well off technologically. They could not engage in war because they were mutually assured of destruction. Currently, a number of states have the ability to produce weapons of mass destruction. For instance, countries such as India and Pakistan have the ability to produce nuclear weapons. This is very dangerous to world security, especially when such weapons get into the hands of terrorists (Hudson, 1998, p. 19). Iran and North Korea are some of the countries that are believed to support terrorism in the world. They agree to enter into agreements barring them from producing nuclear weapons yet they do not honor the accords. For instance, Iran has always claimed that it will use nuclear energy to support its domestic energy supply. The problem arises when nuclear weapons get into the hands of terrorists. The Gap between the South and the North The third problem facing the United Nations in the current international system is the gap between the poor and the rich states. Studies show that the gap between the south and the north is ever increasing. The problems facing countries of the south is how to develop. However, scholars blame colonialism for the problems facing the south. The effects of colonialism were severe to an extent that solutions to problems are inapplicable (Khalid 2012, p. 18). For instance, the issue of anger and insecurity cannot be solved through provisio
