In this paper we discuss the censorship of political statements sympathetic to terrorism as an instance of what Lyotard calls ‘terror’. Our claim is that the traditional approach to questions of censorship of ‘subversive’ politics only captures part of the story; what is at stake is not merely the censorship but at a deeper level, the withdrawal of the possibility to challenge the censorship. This two-tier logic of silencing is what we explore with the help of Lyotard's earlier and later work, first by relying on his analysis of ‘terror’ in the framework of ‘agonistics’, then of ‘terror’ as differend'.
