Hazir, I studied war for a living.
These kind of wars don't end with a deradicalized population. They also don't end with the victor imposing a regime of its choice on the loser without engaging in a long-term occupation. So either Israel fully occupies Gaza for decades, with troops it doesn't have, or it gets Hamas or someone like Hamas. There is no path that leads to a different outcome. You can't just claim something else can happen without providing a convincing explanation of how that will occur. One that doesn't rely on fairytales about people who already loathed the other side waking up and deciding they want peace. Just like I wouldn't expect the Israelis to respond to 10/7 with anything short of a large-scale invasion of Gaza, regardless of their likelihood of success.
