This article examines the way the Book of Joshua in the Jewish Bible/Old Testament was interpreted by some conservative Evangelicals and Charismatic Evangelicals closely allied with Donald Trump, as a model for strategy and organisation around the country ('Jericho Marches') to overturn the U.S. presidential election, culminating in the attack on the US Capital on January 6, 2021. It compares this with the way (then Senator) Barack Obama (soon after announcing his bid for the presidency), also used the Book of Joshua in a sermon commemorating a key event in the U.S. civil rights calendar. He famously called for the 'Joshua Generation' (the current generation of African Americans) to advocate, embody, and demonstrate the values, morality, principles, and practices of the previous generation of the civil rights struggle - love, compassion, justice, and nonviolence in their daily lives, and in their social and political struggles for genuine freedom, justice, and democracy (i.e. applying each of the levels of analysis in the theory of international relations - individual, society, state, and international society). Therefore, this article examines in some ways a very old problem in politics, religion, theology, and international relations - how to interpret the Bible (or any text of a religious type of social tradition). In other ways, it is about the awareness of a more recent understanding of the problem, i.e. why, how, by whom, and in whose interests are concepts, doctrines in politics, religion, theology, and international relations (the holy, the sacred, the secular) socially and politically constructed, interpreted, and implemented with a variety of consequences - violence (war, civil war, and terrorism), or peace, justice, fraternity, social inclusion, and the common good.
