In a series of secret nighttime flights in the last two months, the Obama administration made more progress toward the president’s goal of emptying the military prison at Guantánamo Bay, Cuba, than it had since 2009. The accelerated pace came after an era of political infighting and long bureaucratic delays.

Now 127 prisoners remain at Guantánamo, down from 680 in 2003, and the Pentagon is ready to release two more groups of prisoners in the next two weeks; officials will not provide a specific number. President Obama’s goal in the last two years of his presidency is to deplete the Guantánamo prison to the point where it houses 60 to 80 people and keeping it open no longer makes economic sense.
