War is one of the greatest human evils. It has ruined livelihoods, provoked unspeakable atrocities and left countless millions dead. It has caused economic chaos and widespread deprivation. And the misery it causes poisons eign policy future generations.But, argues bestselling historian Ian Morris, in the very long term, war has in fact been a good thing. In his trademark style combining interdisciplinary insights, scientific methods and fascinating stories, Morris shows that, paradoxically, war is the only human invention that has allowed us to construct peaceful societies. Without war, we would never have built the huge nationstates which now keep us relatively safe from random acts of violence, and which have given us previously unimaginable wealth. It is thanks to war that we live longer and more comtable lives than ever bee.And yet, if we continue waging war with evermore deadly weaponry, we will destroy everything we have achieved; so our struggles to manage warfare make the coming decades the most decisive in the history of our civilisation. In War: What Is It Good Morris brilliantly dissects humanity's history of warfare to draw startling conclusions about our future.
