dont expect full scale war between nuclear countries, it takes only a few hundreds of nukes to end human beings.

There have been 750 above ground nuclear tests since the invention of nuclear weapons. (United States alone detonated over a thousand, but some of them have been under ground) It would take far more than a few hundred to result in the extinction of the human race. One estimate puts the figure at 14,000, and most of the deaths wouldn't be from the nuclear strikes or radiation, but from the resulting debris in the atmosphere blocking out the sun causing world wide temperatures to drop. (nuclear winter). It's estimated that only 6,000 nuclear weapons are functional enough to be launched at a moments notice.
