I'm idly wondering if Iranian adventurism since Iraq has been to their own detriment as much as American adventurism in Iraq and since has as well. Military operations, even covertly, ain't cheap, and in Syrian it hasn't been much covert. Have to wonder if absent those interventions, the protests we see today wouldn't be happening. Because while the populace wouldn't be happy with the morality police, they would perhaps have fewer complaints about economic and other issues as well.
Would be deeply ironic if in the long run, the War of Iraq not only destabilized and weakened America, but also did the same to Iran as well, despite being the ostensible beneficiary of that conflict. And it seems like al-Sadr's camp is moving away from Iran more and more, so much for having a sphere of influence over Iraqi Shia.
