Yellow cheese and bread would be fine with me if I was in prison as an enemy combatant and suspected terrorist.
Such detention is usually indefinite, or at least usually lasts until whatever conflict ends, and POWs usually do not have a right to counsel.
Stress positions are torture and that's not a subject I know much about from an international law standpoint. If it's not illegal it should be.
But here you are once again without enough information to form a strong opinion, getting emotional, and reacting as if you have a real good idea of what's happening in this video, which you do not. Are they stress positions that the inmates are forced to maintain for hours at a time, or were they told to get on the ground with their heads down and legs crossed so the cell could be opened safely for whoever that is touring the facility?
The video and audio are cut up and spliced. You have no idea what the speaker is talking about when he says "this is how it should be after October 7." Does he mean they should be in prison? Does he mean they should not be moving or talking? Does he mean they should be eating only white bread and yellow cheese? Does he mean they should be in stress positions being tortured? Who knows? Not me, not you. And this is how we got here: people reacting to the worst half of a story and automatically assuming the worst possible explanation. That's just not how I operate; I can see that I do not have enough information to have a strong opinion about this video or photos, so I don't have one.
