This is pure conjecture but I wondered what an alternative explanation other than gauging the size of their arsenal for the Russian's wanting more info on the British nuc's. My wacky theory is that they needed the #'s to verify intel and with the numbers they found out it wasn't correct. They then offed the spy providing bad information. Obama's mantra if it just saves one life was violated in this case.
