war in Europe broke out a week later with the invasion of Poland, which started on September 1. Thus, collective security may not always work because of the lack of commitment and the unwillingness of states or the international community to act in concert (Mingst 1999). United Nations The 1945 United Nations Charter contains stronger provisions for decision-making and collective military action than those of the League of Nations Covenant, but it represents not a complete system of collective security but a balance between collective action and the continued operation of the states system, including the continued special roles of great powers. States in the UN collective security system are selective to support or oppose UN action in certain conflicts, based on their self-interests. The UN can be somehow seen as the platform for self-interest purposes for members in Security Council because of the permanent members' veto power and the excessive assistance or aid, which have made those states to act unilaterally and to ignore the approval of or to violate resolutions of the Security Council. The Iraq crisis is a clearer example: "Rather than seek the global interest of peace and security through stability in Iraq and the Middle East region, the domination oriented members amassed their vast economic, diplomatic and military resources, captured and brazenly subjugated Iraq to an unprecedented condominial regime serving their economic interest under Iraq Reconstruction Programme" (Eke 2007). In addition, the lack of geographical spread of members in the Security Council causes an imbalance in the role of maintenance global peace and security. The voices of small countries can be heard, but policies are not adopted in response to them unless they serves the great powers' interests. However, collective security in the UN has not completely failed. The role of the UN and collective security in general is evolving with the rise of civil wars. Since the end of World War II, there have been 111 military conflicts worldwide, but only 9 of them have involved two or more states going to war with one another. The others have been civil wars in which other states have intervened in some manner. That means that collective security may have to evolve towards providing a means to ensure stability and a fair international resolution to those internal conflicts. Whether that involves more powerful peacekeeping forces or a larger role for the UN diplomatically is likely to
