Its not pointless the USA had a big image damage because of the iraq war and a lot of Muslims turned against usa and western civilziation. The extremist where always like this but even the calmer ones started to doubt the USA.
The Iraq war affected the people way more then you maybe think. They are actually pretty pissed because of Iraq. It caused a lot of damage. Because the extremist sold the iraq war as a war against all muslims to the people and they bought it. And yes Iraq is a democracy but without power and if the US will leave the country then the extremist will start to take over the country atleast they will try. It wont have a good end.
I havent heard good things about the circumstances in iraq. They told me it was horrible the country is a mess. And I really hope it will be like you say and Iraq will be a stable democracy but I fear this wont happen.
The future will show if the iraq war had something positive. And I know for sure that the Iraq war was bad for the image of the Usa in muslim countrys and even in the west. Thats for sure. I dont remember people saying bad things about the usa right after 9/11 but this changed quickly after there were discussions about iraq. Obviously you wont recognize it if you live in the US but It happened definetly.
I think we should stop here this leads us nowhere..
