Why did we just set six hardcore jihadists free?

Long War Journal has in-depth profiles of the six Gitmo detainees being transferred to Uruguay.  Well-trained and nasty as hell.

And get this: It amounts to setting them completely free:

Outgoing Uruguayan President José Mujica has made clear that Uruguay would not hold or restrict the six Guantanamo detainees who were recently resettled in his country.

"The first day that they want to leave, they can leave," said Mujica in a Spanish-language interview with state television TNU.

The release of four Syrians, a Tunisian and a Palestinian on Saturday represented the largest single group to leave Guantanamo since 2009, according to U.S. officials.

In the interview Mujica -- a former leftist guerrilla who was jailed during Uruguay's 1973-1985 military dictatorship -- said Guantanamo "was not a jail, it's a kidnapping den," adding that a jail suggests a "minimum of jurisdiction."

A U.S. official said Uruguay agreed to "security arrangements" and that the six would be "free men," though declined to say whether they would be allowed to travel abroad.

Uruguay's president-elect Tabaré Vazquez, who takes office on March 1, said he also supports hosting the men as a humanitarian gesture.

Who among the post-American overlords came up with this bright idea and why?
