I did not read the article, so all I can say is that there are strategic missile heads and non-strategic missile heads. Under the START II treaty between the U.S. and Russia, each country is working on reducing its number of strategic nuclear warheads. There is little talk right now about non-strategic nuclear warheads. The number of non-strategic nuclear warheads Russia has is something that concerns a number of our allies.
