But again, I'd say it's naive to think that the ME was in great shape before whatever starting point you choose to pick. Wahhabism has been a negative influence long before any of the events you list. The Muslim Brotherhood is also older than these events.
It's not that US interventions have been the absolute cause of everything, just that they tend to make a bad situation worse.
Remember, I've never claimed that the West's interventions in the ME have been well executed.
Do you think that the problem was not the interventions, but the execution of the interventions?
If so, knowing the track record, why would you advocate any more?
If a large proportion will be costly failures that damage your economy and make things worse, why not do nothing?
One of the problems we have today is that people see a bad situation and think that we must "do something".
It's like the person who gets a cold and goes to the doctor and demands antibiotics, just because they think they have to "do something". The antibiotics both cost money and would have only negative effects, the best possible response is to do nothing and wait for the cold to pass. Maybe you take a few precautions to make sure it doesn't get any worse, but you can't make it go away no matter how much you would like to be able to.
Sometimes you just have to accept there is nothing you can do. To think everything is your problem to fix is hubristic, especially given the evidence of the effects of doing something.
It's ironic that 60 years ago the US was overthrowing secular democratic regimes in Iran, and know they would kill for one. Then recently they had a war to install a democracy in Iraq, now they are a major backer of a military dictator who overthrew a democratic regime in Egypt.
Politicians don't know what they want, can't predict the effects of their actions and are driven by domestic political demands. That's why they are doomed to repeated failures even if there is the odd success in amongst them. The execution will almost always be flawed and the effects unpredictable, this needs to be foremost in the mids of those who advocate such actions.
