Nukes can't be used by the US. Anyways, the EU would have an objection.
Actually,
this report shows that we are at an escalated level, but that we are not yet at war.
Actually, I'll disagree with you

: I think it's wrong to kill innocent people. I think you may have misinterpreted the "nut-job"'s intent: to tell Saddam to quit using people as shields. A secondary message is to tell the attacking country to avoid killing civilians at all costs.
Under a UN sanction, it is strictly forbidden to cause any civilian casualty, under any circumstances. IF however an individual country declares war on another, then that rule is out, and it's up to each country to apply their own (democratically set?) rules of war, and respect any related treaties.
My question would be this: can the UN force the US to accept a UN mandate to attack Iraq? If not, would the US accept a UN mandate?
(BTW, nice research on the weapons! Where did you find that info?)
