The statement about 31435 remaining nuclear warheads is of course a provocatively false precision. No one can provide any exact information about how many nuclear arms there are. This in itself is rather scary. There is also an issue of making a distinction between warheads in alert, in storage and those being dismantled. In the March/April issue year 2000 of the Bulletin of the Atomic Scientists magazine there is a table over the number of nuclear warheads globally:

According to this table the total estimated number year 2000 is 31535 nuclear warheads with the following distribution among the five nuclear powers:

USA	10500
Russia	20000
Great Britain	185
France	450
China	400

The inventory of nuclear devices in India and Pakistan is negligable in this context (although not politically).
