The "deterrent effect" of Guantanamo on terrorists cannot be confirmed. This is mainly due to the fact that terrorists' feelings or fears in regards to the Guantanamo Bay prison cannot be statistically gathered. Similarly, the terrorists posing a threat to the safety of Western Nations are typically so ideologically fanatical and assured that their path is the righteous one, that there is nothing that would persuade them otherwise, including the risk of imprisonment at Guantanamo. These are often people who are willing to die for their cause.
