Why am I not surprised.
Via Ross Douthat, I ran into this Slate article about the Letter of Last Resort:
At this very moment, miles beneath the surface of the ocean, there is a British nuclear submarine carrying powerful ICBMs (nuclear-armed intercontinental ballistic missiles). In the control room of the sub, the Daily Mail reports, “there is a safe attached to a control room floor. Inside that, there is an inner safe. And inside that sits a letter. It is addressed to the submarine commander and it is from the Prime Minister. In that letter, Gordon Brown conveys the most awesome decision of his political career … and none of us is ever likely to know what he decided.”
