Oh, and there was a "nation" of Iraq before we got there. What is happening there is the establishment of a government representative of the Iraqi people.
BIG difference between the reality and your claim.
Well yes and no isn't it? Yes it was there before we got there this time. No it wasn't before we 'got there' (there being Europe) and stuck our nose in a colonial/trade war in 1917. Would the nation of Iraq had existed if the European powers signed treaties without US intervention? Perhaps, perhaps not.
It was a nation ran by a ruthless dictator and his tribe ruled. Tell you what as soon as we leave the radical Clerics will put one as bad or 10 times worse. And guess what? He'll have a nice new country and equipped Army all trained by guess who? Didn't we learn anything from the first time we tried that there?
