Guantanamo 2

People are treated bad in most countries, but most countries are silent about it. A contrast is the USA where places and phenomena like Guantanamo are discussed openly, if slowly.
It seems that Guantanamo was started from the assumption that it is possible to get information by using hostile but new methods. If this was a success it has global interest.
But was it a success? One test question is if Guantanamo can be closed or not. If it can not be closed, it means that the methods used created tremendous embarrassment and enduring harm to the nation behind. Is this good? Is the cost/benefit analysis positive?
Those who were in favor of the Guantanamo methods now have to prove that they were right by showing that Guantanamo can be closed. Anyone who claims it is impossible to get rid of Guantanamo shows that the experiment was a failure, and a long lasting one.
