Of the governments you mention....Iran is as guilty, Saudi Arabia may be too. Turkey and Pakistan's governments are relaible allies in this. Heck in the U.S. you can find Islamic extremists just recently 6 where apprehended in Buffalo, NY.
So why Iraq, we have to start somewhere, and people smarter than you and I have chosen to start with that criminal Saddam Hussein.
Now that you say this, Turkey is indeed an interesting prospect for the future. I think that Turkey has several important attributes indicating that they are a potential future great power. Turkey itself is a strategic location, I suppose, because it neighbors the former Soviet Union, the Middle East, and the Balkans, which are countries that possess key interests for the United States.
I think that Turkey's oil resources are pretty limited, but the interesting natural resource that this country does possess is water. Turkey controls at least the headwaters of the Tigris and Euphrates Rivers, which gives it a strategic control over the water supply to the states south of Turkey, which would include Syria and Iraq.
I think that the issue of water supply has caused significant conflict between the tribes and clans of the Middle East. Deserts are not a good candidates economic investment and development mainly because there is no reliable water supply.
