Not to get too tactical/removed from the horror that's occurring in this situation, but this is becoming increasingly dangerous for Netanyahu. The more troops he sends into an open battlefield that's likely going to be full of traps, IEDs, possibly mines, and guerilla fighters, the more likely he starts losing large numbers of troops at a time if they're deployed incorrectly or caught off guard/trapped.
He's obviously relying on overwhelming force to crush the resistance that Hamas will offer but that is exactly what guerilla tactics are designed to deal with. I don't like the optics here, and furthermore I don't think Netanyahu has a good military assessment of what he's actually about to do -- he's just reacting as violently as possible to curry favor and reassure people that he is the security PM.
That facade is going to fall away pretty quickly if they don't score major victories with minimal Israeli casualties. If it gets messy and they get bogged down, it's going to further elevate the pressure of the situation, because he obviously cannot afford to be caught with his pants down again.
