the real narrative is that the idf is faced with a race against time to rescue them before they are killed. there will be no "negotiation".
this is why it is against the law in the united states to negotiate with terrorists and why biden should be impeached for negotiating with hamas.
a small percentage may be lucky enough to get rescued. most will not be.
this is the actual choice facing the israeli government in terms of what they are actually able to do: to make decisions allocating resources expended on rescue operations, to determine what is feasible and what may backfire.
it may turn out that these six people were killed because the idf was on it's way there. that just demonstrates the point - there is no way out other than through special operations by the idf, when they are feasible. they were never going to be released. they were always going to be killed when it was most beneficial for hamas to do so.
