Mead has some spot on analysis over at Via Media regarding the future of the Iranian Hardliners

Moderation Postponed in Iran

Maddog has long believed that the Iranian Hardliners are a fixture, and their presence should not alter resumption of US-Iranian relations, or the return of Iran to the family of nations. Obama did the right thing by negotiating an elimination of sanctions, and the core trade deal, but failed to address the nuclear issue correctly. 

Maddog suspects the Mead correctly understands and analyzes the reasons behind the Iranian need for the Hardliner/Shia True Believer stance, but does not believe that hatred for the US and Israel needs to be as significant a feature as it has been in the past. The US needs to help Iran recalibrate the external enemy from the US/Israel to the House of Saud/Wahhabism. This would not eliminate the US/Israel as an antagonistic element in the Iranian pantheon, but it would allow the Iran to sublimate the US/Israel and replace them with the House of Saud/Wahhabism. 

The main thing for the US to do is to stay as hands off in the Middle East as is functionally possible. We need to allow the parties to short out their differences, even if this means going to hot war. However, maintaining diplomatic relations should allow the US to help avoid that outcome, while the parties engage in petty, proxy war actions. 

The ultimate goal is for both sides, the Shia, and the Sunni to be weakened to the point where they agree to a doctrine of live and let live, as opposed to the eliminationist rhetoric they spew today. The goals lead to an Islamic version of the Protestant Reformation.

In order to obtain these goals, the US and the first world will need to rely on its businesses to trade with the Iranians, and for trade to begin softening some of the antiWest rhetoric. This will naturally cause the Hardliners to shift the harsh rhetoric onto another enemy, likely the House of Saud/Wahhabism. 

Luckily we have the best crop of politicians in human history - sarcasm alert! Sigh!
