The international order put in place after World War II is rapidly coming to an end. Disastrous foreign wars, global recession, the meteoric rise of China and India, and the Covid-19 pandemic have undermined the power of the West's institutions and unleashed the forces of nationalism and protectionism around the world. Britain faces unprecedented dilemmas: how do we influence events outside the EU? Can we protect ourselves from cyber attacks and terrorism? Will we accept our diminished role in the international arena? In this lucid and wide-ranging book, one of Britain's most experienced senior diplomats explores how the country moves forward, arguing that international co-operation and solidarity are the surest ways to prosper in a world more dangerous than ever.
