This war has made Iran and China more powerful.
Talabani has signed agreements to buy weapons and cooperate economically with China.
Iran is about to crumble from within, and the Great Satan's perch next door in Iraq was certainly not on the Mullah's wish list of things Allah could bequeath to them, prior to the Iraq invasion. China's emergence is a result of the embrace of a quasi-capitalist economic expansion, and has thus neutered its belligerent bent by making most of its potential enemies customers. Whatever they are, it is not because we took out Iraq.

And why shouldn't they? The premise of the article you posted was that this war is too costly. I simply pointed out some possible positive outcomes. What you point out is not only not necessarily negative, but it is questionable that either assertion is a result of the Iraq war. Would having Saddam still in power make for a better world?
