The Cold War ended some years ago, with the fall of the Berlin Wall and the collapse of communism.
Russia and the USA, the former adversaries in the Cold War, have negotiated a number of treaties relating to their massive stock piles of nuclear warheads; with the intention of making the world a safer place.
One action that they have taken to improve safety, and to lessen the chances of war between them, is to change the targets of their warheads; so that they are no longer targeting each other.
That is excellent.
However, I have one small question; if they are not targeting each other, who precisely are these warheads now targeted at?
