Nukes in war... I often ponder over this. I think the only time that Nukes would be used would be attributed to the wounded animal syndrome. It's beaten, on it's last legs, and lashes out with everythying it has. If a nuclear power is beaten and facing destruction then it is quite likely to use Nukes as one last kick in the groin to its enemy. They are terrible, horrible things, and if there is a massive nuclear exchange there is not going to be much of a world left for us, and society would crumble obviously.
I know that with progress comes terrible technological power, but hopefully one day we can make ourselves technologically intelligent that we would see the absolute folly in nuclear weapons.
A nuclear war could happen, but i hope to the almighty that it never does.
Rich.
