While Ukraine holds back Russia's onslaught, Moscow has been working hard at rebuilding its army for the next invasion. But for the past 30 years, Britain and Europe have been running down their armed forces and defence industries, thinking that war would never come. Most of the continent banked an increasingly illusory 'peace dividend' while outsourcing defence to the United States.

Now, change in the US and clear intent from the Kremlin have set Europe scrambling to rebuild its defences. But will it be enough, and can it be in time?

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. If the freedom and prosperity that the continent takes for granted are to be preserved, the sacrifices required will affect everyone, without exception. Above all, Giles calls for new leadership in defence of Europe as the US steps aside and warns that the UK's brief opportunity to set the pace has already been squandered.
