Glenn Greenwald sees it in his new book, "A Tragic Legacy":
The president who vowed to lead America in a moral crusade to win hearts and minds around the world has so inflamed anti-American sentiment that America’s moral standing in
the world is at an all-time low. The president who vowed to defend the Good in the world from the forces of Evil has caused the United States to be held in deep contempt by large segments of virtually every country on every continent of the world, including large portions of nations with which the U.S. has historically been allied. The president who vowed to undertake a war in defense of American values and freedoms has presided over such radical departures from the defining values and liberties of this country that many Americans find their country and its government unrecognizable. And the president who vowed to lead the war for freedom and democracy has made torture, rendition, abductions, lawless detentions of even our own citizens, secret "black site" prisons, Abu Ghraib dog leashes, and orange Guantánamo jumpsuits the strange, new symbols of America around the world.
And yet this tale of Manicheanism gone awry, of a utopian vision ending in a dystopia, of the terrible dangers of any moral crusade that sanctifies "any method necessary" (in Giuliani’s language) in its well-intentioned pursuit of evil is not a new story. It is one of the oldest stories human beings have told to themselves. Human beings seem to need to relearn it with each generation; and I can only express remorse that, in my time, I needed a lesson as well.
The genius of the American constitution, however, is that it provides the framework for such immoral moralism to be checked and moderated. Alas, we have also seen these past few years how dependent such a system is on the integrity and courage of the people in it.
It depends on an elite willing to stand up against their own power, and it depends on a people alert to the erosion of their freedom. Today, both guardrails against tyranny appear weakened, and the pushback against a radically authoritarian executive has been weak. We have an elite class in Washington either too cowardly to stand up to the power grab or too co-opted by the perquisites of power to care. And we have a people seemingly content to watch freedom being stripped from them – because, right now, it’s 
mainly people with brown skin and funny names being railroaded by the executive branch. Al-Marri and Padilla can be distanced. And the Hollywood fantasies of Jack Bauer can distract from an honest moral assessment of how far we’ve degenerated in so short a time.
There is still a chance to repair the damage – but given how much we have lost since 9/11, the constitutional consequences of another major attack are likely to be terminal to the American experiment in liberty. If a Giuliani or a Cheney is in power on such a day, we can kiss goodbye to the constitution. If I sound overly alarmed by what has happened to American liberty, it’s because I honestly didn’t expect to see habeas corpus, the most basic freedom we have, so casually thrown away and torture so casually enshrined in the American system. I never believed an American president would not only claim but exercise the power to detain any person in America and jail and torture them with impunity – indefinitely. But these are the facts; and my own book was an attempt to account for them within the conservative philosophical tradition. Glenn Greenwald comes from a very different place, but we have sadly come to the same conclusion.
America has exchanged some if its basic freedoms for the patina of phony security – and so easily. The Republican party, to its historic shame, has been the main vehicle for the replacement of doubt, empiricism and calm judgment with certainty, fundamentalism and raw force. We have terrible enemies abroad, seeking to destroy our way of life. But this truth should never blind us to the danger within as well. Al Qaeda can only give us death. It is up to us to surrender the liberty they despise. In so many ways, we already have.
