Weltmacht Usa by Emmanuel Todd

The book argues that apparent U.S. global supremacy is unsustainable: military overreach and unilateral interventions mask deep economic fragility (rising debt, hollowed-out industry and consumer-credit dependence), while social and demographic fragmentation and growing inequality weaken domestic cohesion; together these factors, amplified by an interventionist ideology, presage a relative decline of American hegemony and a reordering of world power.
