Right now someone is devising a tactical operation for a full ground invasion of Gaza to destroy Hamas political and war fighting capability. That is the publicly stated objective. A massive obstacle to success is the dense civilian population. I do not think their game plan is killing their way through civilians. Aside from moral objections, such acts would risk necessary sustained US logistical support. However, precision airstrike alone is insufficient.
I guess I’m trying to isolate and analyze the tactical problem and assuming there are imposed political constraints regarding acceptable collateral. And tactically, this is a nightmare.
For now Israel can lay siege to Gaza, the water, power, food, medical are all cut off, they don't have to fire a bullet, just keep taking out known Hamas locations. The people know it's coming, Hamas knows it's coming, and likely Hamas is stocking up these places with women, children and the infirm so they will have images for social media of the "mean Israelis", which is part of the plan, to try to turn the shock from Hamas to Israel as the press turns on them with articles about killing kids, women and other non combatants in Gaza.
Not sure there is a good solution, which is part of why this act was perpetrated, everyone knows Hamas is a barbaric terrorist evil organization of zealots and crusaders, the actions they took are not surprising, disgusting yes, surprising no. Palestinians dancing in the streets around the world rejoicing in the Hamas barbaric acts are not helping the cause either.
It's an impossible situation, brought about by psychopathic savages who absolutely need to be removed from the face of the Earth, but they hide behind women and children. I don't have an answer, but I know what is going to be done, and in it, innocent will die. And as always from time immortal, all that will be left is mourning the innocent unfortunate on both sides.
There is no easy solution. Other documented measures have been tried for decades and exhausted.
Long after the resulting tent city to come, is gone from Gaza, what will be built? No more hate, one can hope.
