US nuclear weapons

Obama has promised that the US would work towards the elimination of its nuclear weapons. The US and other nuclear weapons states are bound by the NPT to do so--and the NPT came into force in 1970, so they're a bit late.
As FPIF notes, "There is a simple test of the direction of policy: follow the money. In 2008, the United States spent at least an estimated $52 billion on its nuclear weapons program."
So as long as the US does not spend less on nuclear weapons, those promises will remain meaningless.
FPIF also notes that previous presidents JFK and Reagan also made promises similar to Obama's, but nothing significant happened, so it would not be the first time promises are made but no actions are taken.
