Stories are beginning to dribble out about how the Israeli hostages were treated in captivity. I recommend you not read them if you run across them. For one thing some are pretty horrific and for another there is absolutely no way to verify them.
IMO the Israeli government and Israeli Defense Force are erring in not getting out in front of these stories to manage the narrative that is emerging. The risk is that a public uproar could greatly limit their alternatives.
One other observation. Unless Hamas starts providing “proof of life” it will certainly start looking as though a lot of the hostages who haven’t been released are actually dead. I’ve sort of assumed that all along.
