First set of key words being voluntary refusal. It isn't completely voluntary, is it?
The military has said that some prisoners are pressuring others to join the hunger strike, and that some of those being tube-fed occasionally eat regular meals or voluntarily drink nutritional supplements when they are removed from their cell blocks and are alone with medical personnel. . . -- American Medical Association questions Guantanamo force-feedings
I know I'm being idealistic and picky here. I am reading your links in full before I post. First, "some". So, not "all", not "most", not "half". Second, "pressuring". If this is in the form of "peer pressure", i.e. non-physical persuasion, is that particularly unexpected in a harsh "us" vs "them" environment? I refer you to the Stanford prison experiment and its UK counterpart as to how quickly that "us" vs "them" mentality can form even amongst random Western civilians, including hunger strikes. Third, "alone with medical personnel". So, however momentarily, they weren't in that "us" vs "them" environment?
Second set of key words being capable of forming an unimpaired and rational judgment.
So we have almost 100 mentally ill people being kept in an extra-territorial maximum-security military prison instead of a (military, even) mental hospital?
100 out of 179 is a pretty big fraction. It is also oddly close to the number of inmates on hunger strike.
The ones that are left in Guantanamo are pretty much the hardcore. They were willing to give their life for the cause if need be. They have previously engaged in synchronized suicide attempts as a political attack. The suicide Jihad continues, just without bombs in this case.
Um. This might be a stupid question, and feels quite surreal, but: if they truly want to kill themselves, but this time without killing anyone else, and the only alternative (that we're willing to do) is - by our ethical standards - to perform torture upon them, why are we lowering our standards?
But to go on. From your link, "None of the five detainees believed to have killed themselves at Guantánamo Bay have any mental health issues noted within the files. However, all have a record of alleged disruptive behaviour and non-compliance. Most are among the 25 detainees who the files say went on hunger strikes." So we apparently have - had - at least five detainees potentially "capable of forming unimpaired and rational judgements" who killed themselves rather than submit to prison authorities.
Furthermore, "Yasser Talal Zahrani, one of three prisoners who killed themselves on 10 June 2006, was noted to be of low intelligence value", (note "value", so it's referring to military intelligence not personal psychology), "with "unremarkable" exposure to jihadist elements." So are we sure it's just the "hardcore" ones that are "willing to give their life"?
This is the country - the US, I mean - that has both a strong democratic tradition (CIA World Factbook) and the world's highest incarceration rate (International Centre for Prison Studies). What exactly does that say about us? (and yes, I know I keep using "us" and "we" and such, despite not being an American citizen, but the jokes about Australia/Canada/other being the "51st State" exist for a reason, and I was named and raised by a family that likes Westerns, so I associate even though I'm foremost Australian).
"Give me liberty, or give me death!" - attributed to Patrick Henry, in a speech he made to the Virginia Convention that is "credited with having swung the balance in convincing the Virginia House of Burgesses to pass a resolution delivering the Virginia troops to the Revolutionary War. Among the delegates to the convention were future US Presidents Thomas Jefferson and George Washington." (Wikipedia) Have we decided that while it was good enough for America, there's an exception when we're asked to allow it to our enemies and our prisoners?
"The degree of civilization in a society can be judged by entering its prisons." - Fyodor Dostoyevsky, Russian novelist (1821 - 1881).
Is the reason we want to see Guantanamo in a positive light because it reflects our own?
