that means they've given up all hope. The vast majority support of Israelis support what is being done, but many are concerned it will not be the final answer. I share that concern.
The power, believe it or not, actually resides on the Palestinian side of this. Because if they keep coming back with attacks after this offensive, what is Israel going to do that could possibly be a more hard-line strategy?
They could reoccupy all or part of Gaza. They could maintain full time UAV coverage to spot any launches and retaliate with HE. They could forcibly move some Gazans to the West Bank and destroy their Gaza homes...I could go on. Suffice to say there is much more that could be done, and none of it very nice. Never underestimate the dark depths humans can stoop too.
The element of surprise is what caused all the Hamas casualties. Once they regroup and reorganize, that element will be gone and then its back to square one again.
That is a common misconception. Israel took out about ~250 Hamas members at all levels, including some senior ones. That won't cripple Hamas, but does provide a lot of upward mobility. The survivors are now going to be much more worried out themselves and organizational paranoia is going to run rampant through Hamas. Israel had a lot of information they should not have had. Putting personnel aside, there is the destruction of facilities. No offices, no records, no comms. Very disruptive. Finally there is the loss of material. The IAF went after every weapon manufacturing or storage location they could find, even targeting labs at the University. Militarily, there is not much left to work with. Regrouping can not solve the infrastructure and material issues. Note that the tunnels to Egypt are also gone now, so resupply is going to be very very slow.
Its clear that Israel wants to displace Hamas in favor of Fatah and the PA. How successful that will be is still TBD. Some here say it will never happen and like Hamas accuse the PA of being collaborators and colluding with Israel. I am not nearly as sure as they are. We will all have to see how that plays out over time.
