The death toll in Gaza is never going to stop rising. Even if there was an immediate ceasefire and humanitarian aid went in now, it wouldn't be over. People are going to be living with long term effects of surviving building collapses, not just mentally but physically, the effects of breathing in all the dust. And the long term effects of dehydration and starvation, of being surrounded by death. Doctors are already talking about disease being an imminent threat.
Israel knows that they aren't just killing Palestinians by carpet bombing them, but blocking food, water, and fuel. They know that and that is what makes them truly evil, they are not defending themselves, they are committing genocide and the death toll will continue to rise for decades to come, ceasefire or not.
