Evangelicalism, due to the reasons stemming from the American history and demographic structure, has shaped the worldview of the majority of American society and has shown its influence from the lowest level of society to the highest officials of the government. However, evangelical Christians are not religiously and politically monolithic. Although evangelicals can be found in almost every Protestant sect in the United States, there have been many different beliefs, various subcultures, and evangelicalism with opposing views. Since the early 1970s, evangelical groups with fundamentalist views, which are also called the neoconservative right, have increased their visibility in public opinion both within churches and through the various non-governmental organisations which they have established and have become an influential force in US politics. This study examines the effects of these fundamentalist evangelical groups on the US policies towards the Middle East during the Donald Trump administration period. In this context, it tries to explain the interests perceptions of evangelicals as a pressure group in domestic and foreign policy, to define the foreign policy areas in which they are particularly interested, and to observe the interactions and connections of the evangelical movement with Donald Trump and other actors under his administration.
