I think it's clear - what was done before is not working (including 2005 Israeli disengagement from Gaza, humanitarian aid and donations). It's clear that Hamas are dark age scum that need to be dealt with force. It's also clear that most of the population of Gaza supports Hamas, and that Hamas will also will use them as body-shields.
Now, I was born in a 3rd world country and had to deal with a lot of scum. You can't have a conversation with people like those: any concessions you make - will be considered as a weakness and you will be pushed even more.
I don't support Israel in what they do, but I don't see any other options I would choose if I was them.
If you disagree with that statement then I invite you to read more about the organization history, their worldview, their goals and actions.
Personally I do not believe it is conscionable to drop a bomb on a bank where the staff is being held hostage even if it would probably hit the robbers.
Raz Segal, an israeli historian and expert in modern genocides has called this "a textbook case of genocide." Is this where you stand on it? Or is there some sort of middle ground between genocide and another thing you'd like to occupy?
I am honestly and genuinely curious.
