“... meaning that Hamas would have enough time to move all the hostages out of the tunnels.”
” but they can kill the hostages any time they please for that matter.”
Or they could leave a dozen hostages inside and have Israel take responsibility for killing them. Thats the Hamas way.
I am sure the Israelis have taken that into account. There is little they can do for the hostages except threaten reprisals. Given that they are already committed to killing all the leaders of Hamas, Hamas leaders have little to lose. Making concessions for promises to spare hostages only encourages hostage taking. It is a cold calculation, but rewarding hostage taking only encourages hostage taking.
Western sympathizers - and those who are masking their hostility to Israel as humanitarian concern - who then fetishize hostages only encourage hostage taking.
