Unfortunately, some of you don't seem to be able to think in other cultural patterns than American.
First of all, nukes are bad, but you should be more scared by biological and chemical weapons. A modified flu virus, like Ebola, or other nasty disease like anthrax or tularemia would wipe out a city just as a nuke would. And since the disease takes a few days between first contact and first symptoms, it's even easier to sneak into a foreign country. A simple suitcase, or bottle, thrown into the water source of a large city, for instance, will very likely kill it.
As for nukes, Saddam can destroy the oil fields in Saudi Arabia and/or the United Arab Emirates. That's his deterrence, ace in the hole, and that's why nobody actually goes after him. The West hopes that he will die of old age, like Khomeini, or be taken out in a mutiny, like Ceausescu. Killing foreign leaders is one step that NO COUNTRY in the world should dare take, because it would destroy the very essence of democracy. Even if your adversaries are not democratic.
Do not kid yourselves, this game with Iraq is highly political, and it has less to do with "honor", "military" and "human rights" reasons than it does with "oil". The American media is very biased, and creates skewed public opinions, which is exactly what your government wants. European and Canadian sources are a little more objective, at least because thay take more details into consideration, and look at history rather than be persuaded by visceral, reptilian reactions. "Wag the Dog" was a good example of skillful propaganda work, despite the fact that it was a satire.
