Not an expert on this stuff but...
As far as I am aware, the general trend amongst the major nuclear powers *has* been disarmament. Nuclear stockpiles are decreasing not increasing.
It is still politically and militarily sensitive however and for those reasons the process is one that can only be pursued multilaterally.
As for spending money on maintaining them... these things are kind of dangerous. The collapse of the Soviet Union raised all sorts of fears about *not* properly maintaining nuclear material.
