The ethics of diplomatic criticism: The Responsibility to Protect, Just War Theory and Presumptive Last Resort

This article presents the ethical case for diplomatic criticism as a response to mass atrocities and serious external aggression. It argues, in short, that states have a moral duty to criticise the offending parties. More specifically, it argues that diplomatic criticism is often a plausible and preferable alternative to other means of addressing serious external aggression and mass atrocities (such as war, economic sanctions and other diplomatic measures). It also argues that diplomatic criticism is often preferable to doing nothing, and that even if other means are undertaken, states should engage in diplomatic criticism as well. There are two subsidiary aims of the article. The first is to reject some of the worries surrounding international hypocrisy — I aim to show that even hypocritical diplomatic criticism may be obligatory. The second is to highlight the impact on Just War Theory of considering in more detail the ethical issues raised by the alternatives to war, such as diplomatic criticism, and, more specifically, to present a new account of the last resort principle, which I call ‘Presumptive Last Resort’.
