Terrific blog post by Andrew Sullivan. Excerpt:

So how are we where are we now? In Afghanistan, the Taliban has been empowered by the long occupation and the government is as corrupt as ever and fast losing its own people. Al Qaeda have simply moved to Pakistan where they remain safely as long as they duck drone attacks. In Iraq, we actually gave al Qaeda a new opening and had to spend billions and lose thousands of lives to push them back. Even now, we have no guarantee they will not re-emerge in a still deeply divided country when far fewer American troops will soon remain. And through all this, we threw away one core advantage: our moral high ground. Through torture and the mass killings of civilians, through allowing sectarian genocide in Iraq and giving the world Abu Ghraib and Gitmo as symbols of the new America, we even managed to blur the lines between civilization and barbarism. And in this struggle, our political leaders failed to keep the country united, or the alliance intact.

The awful truth is: what 9/11 revealed, and what it was designed to reveal, is that there is nothing we can really do definitively to stop another one. They had no weapons but our own technology. The training they had was not that sophisticated and the costs of the operation were relatively tiny. There were 19 of them. None of the key perpetrators has been brought to justice. Bin Laden remains at large. If you calculate the costs of that evil attack against the financial, moral and human costs of the fight back, 9/11 was a fantastic demonstration of the power of asymmetry to destroy the West.

Everything that has subsequently transpired has merely deepened that lesson. The US is now bankrupt, trapped in Iraq and Afghanistan for the rest of our lives, unable even to prevent the two most potentially dangerous Islamist states, Pakistan and Iran, from getting nukes, morally compromised and hanging on to global support only because of a new president who is even now being assaulted viciously at home for such grievous crimes as trying to get more people access to health insurance…
