Chile was a democracy and US helped overthrow the democracy and install a dictatorship. The citizens managed to resist and recover their democracy after 20 years at a great cost to the country's poor and privatization of Chiles public mineral wealth. Also known as Chiles 9/11. What exactly "worked" here?

Also, are you seriously suggesting that no former communist country is a democracy now? How is this completely random false statement relevant to this discussion?
