I think the hostages are dead.
I’m sure Bibi and the War Cabinet wrote them off as collateral damage. Of course, he cannot say that. But the goal is to save future lives by destroying Hamas right now.
You have to act under the assumption that they are. If you give Hamas any material benefit for taking hostages, you only encourage the taking of hostages. Anyone who deliberately harms a hostage must suffer swift and certain death.
I am afraid that there will be no Entebbe ending to this sad story.
