The next US president must carry a big stick

Just over a quarter of a century ago, the liberal West celebrated triumph in the Cold War. Its victory was underpinned by an evolving strategy of containment, détente, proxy battles and rollback that defeated the Communist bloc without unleashing nuclear war. After unimaginable bloodshed during the 20th century, the fall of the Berlin Wall signalled a triumphal note for the beginning of the next one. Today, less than a generation after the “end of history”, such hopes are all but forgotten, as the global order cracks under a combination of strains either long ignored or wilfully dismissed.
