Over the past century, attempts to normalise relations with Israel have been strongly resisted throughout the Arab and Islamic world if there is not a lasting solution to the Palestinian-Israeli conflict. Israel has long been regarded as a major threat to the security of Arab countries, as well as the security of the region in general. Egypt became the first Arab country to normalise official relations with Israel by signing a peace agreement in 1979. In 1993 and 1994, respectively, the Palestine Liberation Organization (LPO) and Jordan normalised their relations with Israel. Although some Arab countries maintained secret relations with Israel in the past, the Arab position regarding normalisation of relations with Israel has not changed. The situation has changed considerably in recent years, and the process of normalisation has been gaining traction in a variety of fields and becoming more public. Thus, this led to normalisation of relations between two Gulf states, the UAE and Bahrain, with Israel by the end of 2020. It was followed by two more Arab countries, Sudan and Morocco, which opened a new chapter in the history of Israel-Arab relations. This thesis provides a comprehensive analysis of the security and military implications of the Abraham Accords in the Gulf States, particularly the United Arab Emirates (UAE) and the Kingdom of Bahrain. It argues that there has been a trend in recent literature toward suggesting that the Abraham Accords will make the Middle East more peaceful and translate into more accommodationist foreign policies in some Gulf states. However, the author suggests that such analyses of the current political situation in the Middle East are over optimistic and cast a cloud over the future of political conflict in the region. To understand these changes, this thesis stresses the role of the Abraham Accords in changing the regional and political scene and explores how the self-interest' approach (a state's national interests) of some countries in the region has prevailed over attempts to end violent conflict. This research found that the region's countries' current political climate and security concerns are likely to lead to a change in their external political behaviour with each other, particularly in the Gulf states. As political experts and scholars generally believe, external threats drive the formation of military alliances to deter these threats and maintain a balance of power. However, existing studies of military alliance formation have indicated that in some cases, such alliances may lead to increased violence and conflicts between states. The author argue that the formation of an alliance between Israel, the United Arab Emirates and Bahrain to counter Iran is likely to cause Iran to feel threatened and adopt anti-Gulf policies. As such, it is likely to increase rather than resolve the underlying danger of violent conflict for which the alliance was formed. Due to Israel's presence in the Gulf near the Iranian border and the military support Bahrain and the UAE may receive from the US and Israel, Iran is likely to adopt an anti-Gulf policy, potentially posing threats to those countries' internal and external security.
