It is too early to say. Something this fundamental has to be evaluated over a generation or 2. I suspect that the end result will be positive but just not in a politically masturbatory way for either side who wants to declare it was right or wrong today. It certainly will make life a lot easier if we have to attack Iran to have Saddam out of the way. Of course once the region runs out of provable oil reserves, then it won't matter either way what happens there.
