WikiLeaks: US Gave Russia Details on UK's Nuke Arsenal

Now that the "New Start" treaty between US and Russia is in effect, just how did it come to be? The Telegraph says the US got Moscow to play along by giving up some of Britain's nuclear secrets. Citing WikiLeaks documents, it says the US turned over the serial numbers of the Trident missiles it ships to the UK, a disclosure that would give Moscow a clearer picture of Britain's arsenal.

Moscow allegedly pressed US negotiators for details about Britain's American-made missiles, and the US in turn asked for London's permission to disclose them in 2009. London refused, but the US released the serial numbers anyway, according to the Telegraph, which called the information an important "bargaining chip" for the US in the New Start negotiations.
