This research paper will closely analyze US foreign policy regarding religion and the positions taken by current and former regimes in relation to this issue of religion in diplomacy. It will also provide a richly detailed, compelling, and profound overview of how religion has greatly influenced America's foreign relations. This article takes and supports the ideas raised by the two main articles, Andrew Preston, Sword of the Spirit, Shield of the Faith and also by Lee Marsden's article, Bush, Obama and a faith-based US policy. Religion has dominated US foreign policy in the first decade of this twenty-first century. It has become a campaign tool and it is necessary to explain religious issues clearly to woo voters. Since September 2001, when Al-Qaeda attacked the United States, the subsequent American incursion into Afghanistan, the populist overthrow of America's despotic allies in the Middle East, and the surge in Islamic militancy, all of this has created a great deal of focus on influence and influence. importance of religion.

In seeking partners to provide assistance, the next administration should seek those who not only provide assistance effectively but do not compromise broader foreign policy objectives, such as winning hearts and minds and asserting themselves. The use of religious organizations allows the provision of assistance to be distanced from US foreign policy, which is useful in areas where local populations are hostile to that foreign policy. Soft power is always a long-term strategy and goodwill towards US aid providers could, in the long run, yield dividends for the US government at some future date, Marsden (2012)
