The amount of fail that led us into Iraq is still amazing. And the failure keeps coming. There is something poetic in the fact that all our advanced weaponry, all our high technology, interconnectedness and instant pleasures can not cure us of our humanity. We can bug a man's cell-phone, but can't stop ourselves from hearing what we'd like.
Surely there are those, watching the events spreading across the Middle East, who will laud themselves as vindicated. It's more likely that they never saw themselves as needing vindication from the start. I don't know. I don't think ends and means are truly separable. The means you employ are often a statement about your true, unstated, ends.
