This is a book about how civilians suffer in war and why people decide that they should. Most civilian suffering in war is deliberate and always has been. Massacres, rape, displacement, famine and disease are usually designed. They are policies in war. In meetings or on mobile phones, political and military leaders decide that civilians are appropriate or inevitable targets. The principle that unarmed and innocent people should be protected in war is an ancient, precious but fragile idea. Today, the principle of civilian immunity is enshrined in modern international law and cherished by many. But, in practice, leaders in most wars reject the principle. Using detailed historical and contemporary examples, Killing Civilians looks at the many ways in which civilians suffer in wars and analyses the main anti-civilian ideologies which insist upon such suffering.
