The wrong letter at the wrong time
I'm disappointed that thoughtful, generally sensible MPs like Sadiq Khan and Shahid Malik have put their names to a letter telling the government to change its foreign policy in the face of the terrorist threat: http://news.bbc.co.uk/1/hi/uk/4786159.stm
If they want UK foreign policy changed they should argue that on the merits of the policy i.e. is it the right thing to do, not on the basis of whether the kind of crazies who want to blow up passenger jets might be more likely to do so because of it. Otherwise you are giving the terrorists a veto over the UK's role in the world.
The letter reinforces the terrorists' world view - i.e. that Muslims are victims of a great, organised global injustice, rather than combating that view.
The signatories of the letter should be reminding the Muslim community in the UK that British forces remain in Afghanistan and Iraq at the request of Muslim governments to save Muslim lives and enable Muslims who were enduring tyranny to elect their own governments (in the case of Iraq, for large periods of Saddam's rule it was a secular tyranny and the "occupation" has actually seen a great upsurge in religious freedom of expression).
