Using Nuclear weapons on the battlefield will insure a nuclear Holocaust.
I am not positive this is true. Using them against countries without nuclear weapons would not result in a response from those who do. Not sure why it would.
Never the less I can't think of one good reason to use them. A languishing death from radiation sickness is little different, in my opinion, then using chemical agents or bio warfare.
Bush's unilateral attack against Iraq gave justification for the invasions of Georgia and the Ukraine as well as the harsh crackdown in Tibet. It gave notice that such actions were "acceptable".
That's what would happen by using nukes. It would become "acceptable".
