Because if we don't, the potential for chemical and biological warfare occurs HERE. You think we are going to be 'left alone' if we just sit here and say nice things?
"The potential for chemical and biological warfare" would still be a threat to us. Don't you think that maybe there are other countries with those capabilities? Maybe Saddam has some of that technology or at least the directions on how to process it in some other country somewhere as well. What proof do we have that he is planning to attack us with this stuff? None as far as we've been told. Perhaps if we attack Iraq, he WILL use those types of weapons on Americans because he'll figure he has 'nothing to lose'.
