Why has Obama abandoned his pledge?

U.S. President Barack Obama failed to keep his 2008 election promise to close the Guantanamo Bay prison camp at a U.S. naval base in Cuba because the world had stopped watching. Europeans, delighted at his election and pledge to abandon Bush-era torture practices that had sullied the U.S. reputation worldwide, assumed that he would do what he said was going to do. It has taken three years to realise that he missed his self-imposed deadline.
