That post is not quite the full story is it? Israel is pausing aid because Hamas is refusing to agree to Witkoff's proposal. I have no idea who is in the right over this but lets at least get the headline right.
And of course if Hamas would release the hostages Israel would have no reason not to proceed. We seem to need to keep reminding everyone that the capture of hostages has NO jutification whatsoever and Hamas needs to release them immediately.
