Now having gotten that off of my chest, the Guantanamo prisoners still need to be dealt with. It's not much publicized, but many of the prisoners have already been returned to their homes or to neutral nations. Some others have been put on trial and more are likely to be tried in the near future. It's also become very clear that in the light of the Quirin ruling and other legal precedents there's no ambiguity about their status and the legitimacy of holding them and trying them outside of our civilian justice system.
But the fact is that these prisoners are being held by the United States government, on US territory, and we can afford to give them some basic semblance of due process, even if they aren't strictly entitled to it under our law or under the Geneva Convention. This is a situation where it does us as a nation no harm to be generous, and where we could draw the line even more clearly between the United States and the vermin who infest the UN Human Rights Commission.
Every prisoner who is not going to be put on trial in the next year for an identifiable crime ought to be returned to their home country if that country will accept them. This may be a problem, because many of their countries of origin don't particularly want these violent fanatics back, but in those cases some alternative should be found for them - for example letting their home countries imprison and then deal with them under local law with the US covering any expenses. It's likely cheaper to keep them in foreign jail than Gitmo anyway, and also far less pleasant for them. A perusal of the list of prisoners shows some of the problems with releasing prisoners. An awful lot of them are from Yemen, which is basically in the business of exporting terrorists and isn't going to cooperate with keeping any terrorists we give them under control. There's also the problem that some of those we've already released immediately returned to their terrorist careers, like Abdullah Mehsud who was released and immediately returned to his position as one of the leaders of Taliban terror groups in Afghanistan.
