How is this possible in a democracy? What does it say about our country?

I happen to own an old map of Cuba from 1897 that shows Guantánamo Bay, which is along the southeastern coast of Cuba. Here's a photo of a segment of my old map that shows the Bahia de Guantánamo:

Who could have predicted that when our government, in an imperial land grab, "leased" this base from Cuba in 1903, it would become a century later the site of a loathsome prison for Muslim men snatched mostly from central Asia in a "global war on terror"?

In the immediate aftermath of 9/11, the U.S. government needed a place to send prisoners gathered in the chaotic roundup of suspects in the war's opening stages. Among other locations they chose the U.S. naval base at Guantánamo, considered a "safe" spot since it's both isolated and not in the USA while also being far from the eyes of the media. What was an expedient, a temporary holding facility, became permanent. President Obama vowed to close it and failed; President Trump has vowed to expand it with fresh batches of prisoners.
