They have no country to fight for.
It is Saddam's country ... to use, exploit, rape, terrorize and abuse as he sees fit.
I believe Saddam, his sons and family, and his co-conspirators would rather live than die.
I believe the people of Iraq would rather be free, than live in fear and poverty.
I believe that all the above can and will be achieved with the absolute minimum loss of life possible.
I have no evidence (just as you don't), it is just my opinion based on my knowledge and understanding of human nature.
