What happens when one of the twentieth century's greatest Marxist theorists is tested against the world that emerged after unipolarity began to fracture? This Weaponized Intellects review excavates Samir Amin's Beyond US Hegemony? as both a product of its historical moment and a living revolutionary framework, measuring its arguments against China's socialist transition, Russia's anti-hegemonic resurgence, the rise of BRICS, and Amin's own later theoretical development. The result is neither celebration nor dismissal, but a critical reconstruction that distinguishes multipolarity from socialism and argues that only organized popular power can transform the decline of empire into genuine human emancipation.
