Who will defend Europe? The answer should be obvious: Europe should be able to defend itself. Yet, for decades, most of the continent enjoyed a defense holiday, outsourcing protection to the United States while banking an increasingly illusory 'peace dividend'. Now, after three decades of reducing armed forces and drawing down defense industries, Europe finds itself close to unprotected—while Russia is intent on continuing its war of expansion, and the United States is distracted and divided.

In this urgent, vital book, Keir Giles lays out the stark choices facing leaders and societies as they confront the return of war in Europe. He explains how the West's unwillingness to confront Russia has nurtured the threat, and that Putin's ambition puts the whole continent at risk. He assesses the role and deficiencies of NATO as a guarantor of hard security, and whether the European Union or coalitions of the willing can fill the gap. Above all, Giles emphasizes the need for new leadership in defense of the free world after the United States has stepped aside—and warns that the United Kingdom's brief moment of setting the pace for Europe has already been squandered.
