This study investigated the role of different leadership styles within Iran and how such leadership changes influenced Iranian foreign policy. The study utilized event-data analysis of Iranian history and current events and discussed the role of realist and idealist to the development of Iran into the regional power it is today as well as how Western relations played a role in developing Iranian foreign policy, particularly with regard to its nuclear development. The main body of the study drew from the dynamics within Iran, its relations with the West, relations with Israel, and relations with other foreign powers. The event-data analysis also took into account the political and socioeconomic stability and conditions within Iran as it would readily influence the foreign policy-making within the nation. The first part of the study analyzed Iranian society under the Shah and the under the revolutionary guidance of the Ayatollah Khomeini; the second part analyzed the post-Khomeini period in Iran. In addition to reviewing the role of different revolutionary leadership styles within Iran, this study considers the role that Iranian-Western relations have played in Iranian policy-making. Further, this study considers the tumultuous role that nuclear development has had in Iran's foreign relations. Findings showed that there is a relationship between Western presence in the Middle East and growing aggression by Iranian leadership. Moreover, the study demonstrates that the role of revolutionary leadership styles is critical in accessing the manner in which foreign policy decisions are made. The study found that the role of Islam in Iranian politics has brought much contention but found that in the post-Khomeini years, it has not been the central reason for policy decisions. Recommendations were made for the continued study of the role of nuclear development in Iranian-Western relations as this study was able to find some evidence of it having some level of relevance. Additionally, recommendations were made that additional research be conducted with regard to the role of Islam in shaping Iranian foreign policy in the Post-Khomeini era.

自2002年秘密運作的核能設施曝光後，伊朗的核能政策一直是國際爭點且令人費解。若要討論伊朗核能政策是如何產出及其未來的走勢，本文認為伊朗本身的動機才是決定核能政策的關鍵。 本文以「個人－國內政治－國際政治」三層次作為分析架構，首先討論核能政策的發展歷程及其對伊朗的意義；其次分析伊朗最高宗教領袖Khamenei及伊朗政治派系如何影響核能政策；最後聚焦於2009年綠色運動後至2015年JCPOA簽訂這段期間，伊朗最高宗教領袖Khamenei與核能政策演變的關係。 本文發現伊朗的政治菁英對核能政策有高度共識，認為發展核能政策代表著實踐伊朗的大國意識與民族尊嚴、經濟與能源多元化的自主發展以及安全上的保障。另外，從政治派系角度出發，核能政策也被視為派系鬥爭中的槓桿，是政治菁英獲得權力的工具。同時，基於伊朗特殊的政治體制－－教法學家體系，最高宗教領袖Khamenei為伊朗權力體系中的第一人，其態度與政治取向決定了核能政策的走向。而在最高宗教領袖Khamenei決定核能政策的走向時，其必須將國內外政經局勢納入考量，並時時權衡當前的局勢是否會影響其作為最高宗教領袖的合法性。本文認為，若能繼續對最高宗教領袖Khamenei加以觀察，並分析其與國內政治派系的互動，將有助於未來對伊朗核能政策的了解並對伊朗政治帶來更全面的研究。

Juche ideology, created by founder Kim Il-Sung, governs all aspects of North Korean society. This thesis attempts to answer the questions of why and how Juche ideology and the cult of personality surrounding Kim Il-Sung were successfully implemented in North Korea. It is a historical analysis of the formation of the North Korean state that considers developments from the late 19th century to the late 20th century, with particular attention paid to the 1950s-1970s and to Kim’s own writings and speeches. The thesis argues that Juche was successfully implemented and institutionalized in North Korea due to several factors, including the rise of Korean nationalism, the personal history of Kim Il-Sung, the Korean War and resulting domestic strife, and the influence of the international socialist movement. It provides a historical explanation of Juche and its importance within North Korea, which in turn is necessary for understanding North Korea as a whole.
