In this major new assessment of Hannah Arendt's writings on International Relations Patricia Owens provides a compelling case for Arendt's continued relevance to debates about suicide bombing; genocide; the ethics of war; civilian casualties; and the dangers of lies and hypocrisy in wartime. A well-written, cogently argued and entirely persuasive account of Arendt's sustained but largely ignored engagement with war and violence, and how it provides a key to many of her most important political and philosophical ideas.
