Operationally, if Israel succeeds in cutting off the civilian population’s dependence on Hamas for their daily needs, it would essentially pull the rug out from under Hamas as the governing authority in Gaza. 

The people have already lost normal lives, homes, and basic infrastructure that Hamas once provided. Now, if the plan works, even food will no longer come from Hamas — and that’s dramatic.

Diplomatically, if Israel can convince the world that Gaza’s civilians are not starving, it will ease some of the heavy international pressure.
