The history of international relations represents in vain, that the countries when faced with crises, have made many errors. Most of the decisions of countries have usually lead to huge disasters for the international community. This article utilizes the theory of the international community to acknowledge the dysfunctionality of states’ attention to spending for the wars, siege, and boycott, and torecognize JCPOA’s negotiations as a result of cooperation and power. Using force against Iraq and Afghanistan had no consequent but to help grow terrorism in the world. However, negotiations and granting a positive role to an international actor can help the state to cooperate with the international community. The result of this action would be a stable peace. The Vienna agreement, similar to the Vienna Congress, will start a new era in international relations. This is a new era will be based on dialogue, cooperation, respect and adhere to the principles of international law, and respecting the interests of great powers. The author believes thatthe international security and peace in the world would last, as long as international actors support the JCPOA.
