There's no ceasefire and moving to the next phase will make it worse
The very bare minimum for a ‘ceasefire’ anywhere is that the firing must ‘cease’. If the firing hasn’t ceased, it’s not a ceasefire. Sure the firing occasionally ceases, but firing always occasionally ceases. Even in the hottest of wars.
The bottom line is that apart from returning some bodies, Hamas has done nothing to comply with the ceasefire. It has continued launching attacks. Israel in response has struck Hamas.
Hamas has made it clear that it will not disarm. Qatar, which negotiated the fake ‘ceasefire’, backed up the demands of its Hamas proxy at the Doha Forum, for a complete Israeli withdrawal until Hamas does anything. (And then Hamas won’t do anything anyway.)
