It's no wonder such sensitive situations were mishandled. The theoretical magical chain of events that lead to sustained "freedom" was always there, on paper at least, but using the US examples we should conclude that its cost-benefit is waaay way lower than necessary to consider it a useful foreign policy tool.

Of course, an avid idealist might argue that this just means the US (or the world, or the West) just needs more experience to be able to better export "freedom"; and of course it is something we should never stop trying. And even today, even after the whole ISIL/ISIS campaign every place is better off now than it was before. (No Saddam, no Gaddafi, etc.)
