Complaining that the West is to blame for what?
There's a racism of low expectations in some of this. The allies toppled Nazi or Nazi-backed governments all over Europe in 1944 to 1945, and more dramatically toppled the Japanese government by dropping nuclear weapons on large cities. They didn't expect, and didn't get, civil wars: those countries which had been fascist dictatorships (West Germany, Italy) returned to democracy within a few years, occupied countries (France, Holland, Belgium, etc) rather faster, and it only required ten years before the Americans pulled out of Japan. Japan has not, to my knowledge, degenerated into lawless anarchy.
So in the case of the second Iraq war, no-one thought that Saddam was a good ruler, a lot of middle eastern peoples argued he was a murderous despot, and there were constant cries for better governance. Topple the bad ruler, install a democratic regime, job done. Now it's argued that Iraq and its surroundings are so inherently unstable that the best thing to do is to leave a genocidal madman in charge because that way the trains will run on time sorry, because that way unemployment will be kept down by building Autobahn, sorry shoot enough Shia to keep the Sunnis happy, and vice versa.
So America's failing was in not thinking badly enough of Muslims in the areas, and not realising that left to their own devices they'd rather fight protracted civil wars than develop their economy. Cynics may say they told us so, but it's a real case where optimism is being punished. We now know that Muslim countries in the middle east require violent strong men to stop them blowing each other up in mosques, but it's a lesson that had you argued it in 1980 the Guardian would have called you racist.
