"It's perfectly true that al-Qaida and its "takfiri" fellow travellers have an extreme, violently sectarian and socially conservative ideology. But it is simply delusional - and flies in the face of logic and history - to fail to recognise the central link between the terror threat and Britain's post-9/11 actions in the Muslim world.
First, there were no al-Qaida-inspired attacks in Britain before the invasions of Afghanistan and Iraq. There were against the US - starting with the World Trade Centre in 1993 - triggered by the aftermath of the Gulf war, as well as jihadist campaigns in Kashmir, Chechnya and Bosnia. But Britain was not a target until it attacked the Muslim world. If the bombers' real focus was, say, sexually liberal western lifestyles, they would presumably be attacking cities like Amsterdam and Stockholm."
You can read the rest of Seumas Milne's excellent piece on how adopting an 'interventionist' neo-conservative foreign policy has made Britain a target for terrorists here.
