I see that but, i do think Israel should pull back from the constant bombing.
If they had good intel, would they really need to pummel Gaza so much?
Maybe its time to move in on foot now.
You're also assuming Hamas will let Palestinians leave freely. I think part of the reason Israel are weary of moving forward with a ground invasion so quickly is because of the number of Palestinians that are effectively being held hostage by Hamas to use as human shields.
It makes great propaganda for Hamas when they can claim Israel are storming buildings and executing anyone found inside.
