GUANTÁNAMO BAY, Cuba — Nobody has a dementia diagnosis yet, but the first hip and knee replacements are on the horizon. So are wheelchair ramps, sleep apnea breathing masks, grab bars on cell walls and, perhaps, dialysis. Hospice care is on the agenda.

More than 17 years after choosing the American military base in Cuba as “the least worst place” to incarcerate prisoners from the battlefield in Afghanistan, after years of impassioned debates over the rights of the detainees and whether the prison could close, the Pentagon is now planning for terrorism suspects still held in the facility to grow old and die at Guantánamo Bay.

With the Obama administration’s effort to close the prison having been blocked by Congress and the Trump administration committed to keeping it open, and with military trials inching ahead at a glacial pace, commanders were told last year to draw up plans to keep the detention center going for another 25 years, through 2043.
