Donald Trump’s withdrawal from the Iran nuclear deal (JCPOA), his use of negotiations as a stalling tactic while enabling Israeli strikes, and his public lies — such as claiming he would “wait two weeks” before deciding on a military response, only to covertly authorize action — raise not merely political or strategic concerns, but deep moral and theological questions about the very nature of leadership. This concern is amplified by the fact that his base includes many devout Christians who find his bravado motivational and empowering. In this piece, I examine the theological implications of his dishonesty through the lens of ʿilm al-kalām (Islamic theology), and his deceit in negotiations with Iran through the lens of classical Islamic law—particularly in the Mālikī tradition.
