Two years later, and counting, the United States still has prisoners at the Guantanamo Bay detention camp.
After spending three years at Harvard Law School, Obama knew that promising to leave Guantanamo Bay detention camp within a year, was a deliberate lie. The lie to leave Guantanamo helped him to become President. If President Obama had read even one case at Harvard Law School and understood what was involved in landmark litigation, he would have noticed that almost nothing can be accomplished, in less than one year, when the law is involved.
