And he's right. While America has never entirely lived up to its ideals, it has generally pursued a progressive path which has strengthened freedom and human rights, and so deserves to be celebrated as a "beacon of freedom". But when the leader of that "beacon of freedom" establishes gulags, his Vice President tries to overturn a ban on torture, and jokes about the old Soviet Union suddenly seem strangely appropriate, you have to worry. America is as far from its founding values as it has ever been - and moving in entirely the wrong direction.
Hopefully this will change when Bush leaves office. OTOH, the American people endorsed Bush's policies at the last election in full knowledge of what they meant. They voted for Guantanamo, they voted for rendition, and they voted for Abu Ghraib. The sickness is deep, and it will take many years to work itself out.
