Israel is making Gaza uninhabitable for those displaced. Most will have no homes to return to, the places they were told were safe are being bombed, and in the meantime, the whole population is being denied clean water, fuel and food.
Schools, hospitals, universities, places of worship and government buildings -- civil society in total -- are being demolished.
It's de facto collective punishment and ethnic cleansing. Totally disproportionate, indiscriminate and barbaric.
Israel is also supporting/turning a blind eye to settler pogroms and violent disposessions in East Jerusalem and the West Bank.
All of this is strategically short-sighted. None of it will make Israel, or Jews, safer in the medium to long term. Quite the opposite, imho.
