You're wrong. It's not even worth debating. In 1860 you probably pounded your fist about how culturally, religious, and ethnically different Bavaria was and how any unity with it's neighbors to the north was temporary at best. :)
If you think Iraq is going to become Germany any time soon you're going to be dissapointed.
Iraq is closer now to where Germany was during the 30 years war than anything else and that process has to play itself out, which is going to be very messy for a very long time.
