I think there are probably some reasons why Guantanamo is not closed yet:

1. Several countries don't want to repatriate the prisoners sitting there. Many of those prisoners have nowhere to go. Nobody wants them in their country.

2. Fear of reincidence is a factor too. There is guarantee that if any of these men end up free again they won't go back to doing what they did before being captured. Now they have even more reason to hate the USA,s ince many of them were imprisoned for years without formal trials or charges.

3. Prisoners disclosing what happened in Guantanamo is a factor too. What we know of interrogations there is only the tip of the iceberg. It is possible that these men are theatening to publicize what happened to them in Guantanamo. They might not be willing to buy their freedom with silence.

I think Obama was unrealistic in thinking he could close Guantanamo without giving thought to what they would do with those prisoners or how they would be legally processed. Am I disappointed with Obama? No, because I knew from the beginning that the US can NEVER close Guantanamo. The only way Guantanmo will close is if the lease runs out and the Cubans ask for their land back. Then the Gulag will have to move elsewhere.
