Good article (if rather pessimistic ) here by Robert Fisk

This is the key sentence in Fisk's report:
It's the same old problem for us in the West. We mouth the word "democracy" and we are all for fair elections – providing the Arabs vote for whom we want them to vote for.
What the West will be working for is a government wholeheartedly committed to neo-liberalism. It will seem liberal at first and end up authoritarian. Those protesting now will by then be divided between those who seek to find their place in the new order and those who seek something else-which could by then be a clerical regime.
