Possibility of self-criticism and escaping a self-referential morality
"The terrorist is objectively wicked, no dispute about that, in exercising the most appalling form of blackmail by menacing the lives of the innocent. Nothing should qualify this judgement. But this does not mean that the terrorist has no serious moral goals. It is possible to use unspeakably wicked means to pursue an aim that is shared by those who would not dream of acting in the same way, an aim that is intelligible or desirable. The risk in claiming so unproblematic a right to define what counts as politics and so to dismiss certain sorts of political calculation in combating terrorism is that the threatened state (the U.S. in this instance) loses the power of self-criticism and becomes trapped in a self-referential morality which creates even deeper difficulties in the application of just war theory."
