In an attempt to offer a better explanation to international political economy, observers in international relations have made use of diverse theories and perspectives. Among the most notable theories include Liberalism and Marxism. The two theories differ with regard to varying factors and components that impact on global integration. They include the thoughts and principles on such areas as the trade unions, international organizations, state’s sovereignty, multinational corporations, globalised economic processes, and international crime. Liberalism is based under the idea that giving people maximum freedom and liberty would help eliminate authoritarian political regimes, achieve higher levels of democracies, reduce civil wars and civil unrests and as result achieve global peace and prosperity. In Liberalism the government applies little control over freedom. It is also leveled at the same degree of moral standards as its citizens. Liberalism is aims to achieve democracy, peace, free trade as well as international integration. Liberalism calls for commitment to tolerance as well as giving opportunity for right self-determination by citizens. It favors constitutional government which expresses the people’s democracy and that which applies collective rule of law. Liberalism requires that citizens in a state be given the opportunity to realise intellectual and economic liberty; this should form the basis for political order which applies minimal government regulation. In this case, the government’s role is to protect and promote the citizens economic and intellectual liberty. Liberalism also gives individuals the opportunity to follow their own initiatives (Evans and Newnham 1998, p.46). According to Evans & Newnham (1998 p.61) liberalism is founded on four core beliefs in international relations. Liberalism believes that peace can be best achieved by developing and strengthening democratic institutions on a global basis. It founded on the ideology that treaties and laws should be consensus-oriented and that state preference and not state capabilities should be the principal determinants of the conduct of every state. This implies that each state is given the opportunity to carry out an analogy into its domestic level concerning individual motivation of its citizens while pursuing positive international relations. It also believes that a natural harmony would enable nations and individuals make rational calculations which help integrate international interests and national interests. Thus liberalism encourages tolerance of preference through democratic institutions which are strengthened by enlightened educational institutions. This would help promote rational calculations individuals and states and hence reduce the chances of wars. It acknowledges that preferences usually vary in states depending on the type of government, economic system and the culture of the country. Since it is governments that make war and not the people, establishing governments which represent the popular will of citizens and governance systems which employ democracy is most likely to encourage peace (Evans and Newnham 1998, p.62). It is also founded on the belief that disputes are better solved through established judicial procedures which are i
