Israel achieved their main objectives without putting boots on the ground. They destroyed any way for the Muzzy’s to get rocket parts into Gaza. They also destroyed the factories to build them, the R&D shops and destroyed the governmentg infrastructure without destroying food, water and power distribution. And they destroyed the tunnels to smuggle material in. They are also killing Hamas leadership.
What will putting boots on the ground do for Israel when Hamas terrorists are now scattered among the people?
That's why Israel needs to use more powerful weapons. If your enemies hide in a group, then you have to destroy the group to kill your enemy. Besides, any "civilian" who provides cover for these Hamas savages deserves to be killed too.
