This paper is an analysis of the consequences of US foreign policy since the beginning of Trump term. To do so, it initially uses concepts and theoretical notions that do not come in shock with the basic realist premises, we intend to highlight the necessary and singular conditions that allow to explain the unipolar moment. Then one analyses Trump’s foreign policy towards American allies and, taking the theoretical concepts from the first part of the paper, analyses the consequences.
