Well, thanks to the sanctions Saddam got rid of his WMD of mass destruction. So for me sanctions are working. And wasn't that what the US wanted, to eliminate the threat of WMDs? And if you really care so much about Iraqi civilians, US shouldn't have blocked allowed food and medical demands by Iraq which resulted of the death 1.3 million.
The only point here left to argue is if democracy is a better system or not. In my opinion it is. But I don't posses the arrogance to tell a foreign country that it would be better for them as well.
