Interbellum is the period from 1918 to 1939, when humanity, having emerged from one global massacre, not only did not take into account the mistakes of the past, but made every effort to enter a second, even larger and more terrible war. This book tells how various countries, and even entire continents, inevitably rolled towards the greatest catastrophe of the 20th century. About how ambition, the thirst for expansion, the desire to do better and pride, bordering on outright stupidity, led to a terrible global catastrophe. Particularly interesting is the authors' view of countries that did not play the first fiddle in international politics of the 20s and 30s, but contributed to the outbreak of war. In front of you, as it were, is a snapshot in which the world is frozen, choosing, instead of an era of universal prosperity, the most terrible six years of its history.
