A Study of the Role of Thinking Rooms inObama’s Decision-Making about the Nuclear Plan ofthe Islamic Republic of Iran

The purpose of the present study is to explain the role of thinking rooms in Obama’s decision-making about the Islamic Republic of Iran’s nuclear plan. The research method is descriptive-analytic and the results indicated that since thinking rooms as non-official organizations in the USA affect decision-making in that country, we can explain changes in Obama’s policies about Iran’s nuclear plan with respect to the decision-making theory, especially the organizational model. During the presidency of Obama, his foreign policy in terms of Iran’s nuclear plan consisted of 2 stages: the first stage of consensus-building for Iran’s maximum sanctions; and the second stage of negotiation and peace with Iran. Changing the government in Iran caused them to be able to dissuade Iran from Uranium enrichment and some other nuclear achievements.
