If something as vague as "release everyone" or "release all Palestinians in Israeli jails" or whatever is one of their actual demands, it's unfortunate, because it makes it sound more like they're not serious and are just making impossible demands that they know will not/can not be met as an excuse to continue fighting but to give off the appearance of working for peace. Just as if "the eradication of the Israeli state" were one of their demands. But I can't really accuse them of that yet since I haven't seen an actual list of demands and we're both just speculating at this stage.
