My guess is there are no living hostages. I wouldn’t negotiate with Hamas anyway.
I suspect the same.
Keep bombing the crap out of Gaza until nobody there is alive.
Then pave it over.
Just a guess but I would estimate maybe 50% of the remaining given as a number are actually dead. RIP.
At the every end the Arabs will renege and keep some last hostages after lying about them and receiving the Arab prisoners in exchange. Lying to infidels is not a sin.
