I fully expect the Israeli government to be true to their words. They are very trustworthy and I see no reason why they would slaughter civilians in Rafah after all the hostages are released.
My mom agrees with me, too. We were talking about this topic today, I told her how I'll always trust Israel, then she said "okay love", then she covered her face with her hands and would you believe it, she simply disappeared! And not five seconds later, she moved her hands and lo and behold, there she was again! Holy shit, so cool!
It's fucked up, even the fact that they expect the world to take their word for it shows me two things. First, that the international media is willing to just swallow anything Israel says, hook, line and sinker. Second is that Israel simply assumes that to be true from the get-go.
If the media has not held them accountable for declaring safe-zones and then bombing them immediately afterwards, they're not about to do it this time around either.
maybe they feel they need more 'justification' to use as propaganda in the wake of faltering popular support in the west and the ICJ ruling. I doubt Isreal has any intent on honouring this if the hostages are released, either blowing them up and blaming hamas or making up fake hostages and saying hamas still has some after releasing all.
