That's why there were inspectors
IF WE WERE SO SURE WHY WHERE INSPECTORS NEEDED?
Where are they MF? Where are the weapons? Where are the devices to doom as all in Iraq? IF we were so certain how some the US was condemmed by the UN and many countries for going in? Un even called the invasion illegal.
Answer, there aren't any, there wasn't any. The premise of the war was flawed. Show me the evidence of there being WMD in Iraq and I'll gladly admit I'm wrong and your right. But there isn't and won't be any.
Straight from Wiki, you don't even have to go further;
At the start of the war, U.S. officials argued that Iraq and its alleged weapons of mass destruction (WMD) posed an imminent threat to the interest of the United States, Europe and the other nations of the Middle East. The intelligence was supported by British intelligence , as well as given tacit support by Russian and German intelligence.. But the intelligence was also criticized by others.
and weapons inspectors found no evidence of WMD. After the invasion, the Iraq Survey Group concluded that
Iraq had ended its WMD programs in 1991 and had no active programs at the time of the invasion, but that they intended to resume production if and when the Iraq sanctions were lifted.
Although some earlier degraded remnants of misplaced or abandoned WMD were found, they were not the weapons for which the coalition invaded.
Great - a war for a presumption of something that might possibly happen in the future if and when the UN removed a sanction presuming Saddam was still in power and the resources to produce WMD were still there.
Quite a far cry from "THEY HAVE WMD AND WE WERE RIGHT TO INVADE"
Many countries did disagree, but it was about how to proceed, not if we should proceed or not
This statement is completely false. France openly opposed war. One example, top of my head.
This isn't a question of opinion any more MF, this is pure fact. Your argument has about as much merit as me trying to argue gravity doesn't exist. That's how it is.
