I agree. He would be a bigger idiot than they are portraying him as. Brazil now wants nukes; is that because they're afraid Iraq may invade them? Or maybe they're afraid of North Korea coming there and telling them how to live?
They aren't. They make Hilter look like an amature. They are murderous, hateful, vengeful, psychopaths who have killed masses of their own people and now threaten the modern civilized world, basically backing themselves into a corner and have no other choice but to go out with a bang.
Neither their own people nor the rest of the world supports them. When American tanks drive through downtown Baghdad, the people will be cheering them on waving American flags. Just you wait and see.
There is using them, and there is simply that having them gives one the threat of using them. Which has tremendous effects on other countries all by itself.
If Iraq had fully functional and useable Nuclear weapons, could we even threaten to invade? Probably not.
Are we dealing with Korea differently, because they probably do have some weapons? You bet.
Has Isreal avoided another major attack from antagonistic Arab neighbors because it has them? Probably.
Could Iraq threaten attacks on its neighbors, like Kuwait, and keep us from responding, if it had nuclear weapons? Yes.
Everything changes. They don't necessarily have to be used.
