Would We Nuke Iraq?

If Saddam uses chemical weapons on our troops, would we (The U.S.) use a nuclear weapon on them? I read in an article that said if Iraq used a chemical weapon on our troops, we would use a nuke on them. Is this true?

I don't think we would ever nuke Iraq for a few reasons. One we are at war with the regime, not the people of Iraq, a nuke would just kill and destroy everything. Secondly, all those Humanitarian Rights groups would be in our ass and it would hurt our relations with Europe. If anything, I think we'll use that MOAB that we tested in Florida, it's the closest thing to a nuke we got.

i'm pretty sure they already been using that MOAB bomb in iraq havent they?
