Looking at your posts on this thread, it appears you don't understand the international conventions on war. Those conventions don't actually apply to this conflict as it is not classed as an international conflict, but let's look at them anyway.
We know that Hamas put military installations in schools, hospitals and other civilian sites. We know that they use the civilian population of Gaza as human shields. This is a war crime.
If Hamas has sited a military installation in a civilian setting, Israel is permitted to attack it provided it is to achieve a military objective and the action is not disproportionate. Israel has overstepped the mark at times, so some of their attacks have been war crimes, but it is not as simple as saying that every attack on a school, hospital or similar is a war crime.
If we look at how this conflict flared up, it started when Hamas launched attacks on Israel including attacking a music festival. There was no military installation at the music festival. It may be that a minority of those attending were off duty members of the military, but the vast majority were not. This attack was a war crime.
Other attacks were aimed at kibbutzim and moshavim. There were no military installations at any of the targets. These attacks were war crimes.
We know that the Hamas fighters executed some wounded individuals at point blank range as they crouched on the ground. This was a war crime (although I wouldn't be surprised to find that Israeli forces had also committed this crime).
Men and women were gang raped during the attack. This was a war crime.
The bodies of a number of those who had been killed were paraded through the streets of Gaza. This was a war crime.
A number of hostages were also paraded through the streets of Gaza. This was a war crime.
In one of your earlier posts you say that Israel exists, as if this is somehow a killer point. Yes, Israel does exist, but the Covenant of the Islamic Resistance Movement, which was issued by Hamas in 1988 and sets out the organisations aims, calls for the obliteration or dissolution of Israel. It also rejects any possibility of a negotiated settlement. Hamas released a "Document of General Principles" in 2017 which is a little more moderate, but it does not repudiate or replace the original Covenant and, although it does not directly call for the destruction of Israel, it is clear that this is the only way its goals can be achieved.
Israel is also, of course, under attack from Hezbollah which, like Hamas, is backed by Iran. Hezbollah also aims to destroy Israel. Its armed strength is considered to be equivalent to a medium-sized army, and it is thought to be stronger than the Lebanese Armed Forces.
Has Israel committed war crimes? Yes. I would not seek to defend everything Israel has done. Some of Israel's actions have clearly been wrong. Even where Israel has complied with the rules of war, some of their actions have been misguided. But a simple position of "Palestinians good, Israel bad" is, at best, misinformed and, at worst, antisemitic.
