  But political communities other than states may surely face supreme emergencies, even allowing for the difficulties in interpreting the concept, so the way is open in principle for sub-state terrorism to be justified. This is a position that Walzer somewhat reluctantly seems now (in a parenthesis to a later reprinting of the terrorism article) to concede, though it goes somewhat against the grain of the article itself. The parenthetical comments, published in 2004, are: “Would terrorism be justified in a ‘supreme emergency’ as that condition is described [by Walzer in the earlier chapter called ‘Emergency Ethics’]. It might be, but only if the oppression to which the terrorists claimed to be responding was genocidal in character” (Walzer 2004b, 54). There are difficulties in matching the complex meanings of “genocide” to Walzer’s communitarian account of supreme emergency. For one thing, a Nazi victory would probably not have meant genocide for the British community yet, according to Walzer, they were facing supreme emergency. So, the sources of his differential treatment of state and sub-state terrorism remain a puzzle.
