In this essay, I summarize major points of my Ethics for Enemies. I first consider whether torture of a wrongdoer to save his victim could be permissible. In order to do this, I consider whether we may do comparable things to him while he is setting up a threat in order to stop his act, get him to stop it, or otherwise use him as he acts to stop harm to his victim. 1 also consider possible differences between harming the wrongdoer as he acts and after his act in order to help his victim. I next describe my view that the intention to harm and terrorize civilians need not make an act be terrorism or be morally impermissible. I consider what makes terrorism distinctively morally wrong and whether it is always impermissible. Finally, I describe my views that having a right reason is not necessary in order for starting a war to be morally just and that goods that are not part of a just cause may weigh in a proportionality calculation needed to determine if a war is just.
