According to the Guardian the UK is the target for Al-Qaeda nukes if they manage to get hold of them:
UK officials have detected “an awful lot of chatter” on jihadi websites expressing the desire to acquire chemical, biological, radiological or nuclear weapons.
Asked whether there was any doubt that al-Qaida was trying to gain the technology to attack the west, including the UK, with a nuclear weapon, a senior Foreign Office counter-terrorism official said: “No doubt at all.”
The official explained: “We know the aspiration is there, we know the attempt to get material is there, we know the attempt to get technology is there.”
For al-Qaida and jihadis, a devastating nuclear attack on Britain, not just the use of a “dirty bomb’, would be part of the desire and agenda to cripple the west, sources said.
The senior Foreign Office official said: “There are people for whom it would be a triumph for the cause.”
