The threat to the UK and its Western allies from Al-Qaeda related terrorism has declined but groups such as Islamic State in Iraq and the Levant (ISIL) have filled the ‘void’. In response the UK has introduced a raft of measures to increase its security, fulfilling many of its international and regional responsibilities to prevent terrorism. Human rights law is particularly important in this regard as it imposes obligations on states such as the UK to prevent violations of rights, such as the right to life, by non-state actors such as terrorists. This article seeks to employ a theoretical justification for a reading of this approach to human rights and focuses on legislative measures the UK has introduced to protect them. The philosophy for doing so is communitarianism, notably its critique of liberalism, and the post 9/11 revisions to it by communitarians such as Amitai Etzioni in particular.
