Look in the end Netanyahu is defending Israel. I don't think he doing anything most people wouldn't do to protect themselves if they felt under serious threat. Examples from history like the bombing of Dresden just remind of the realities.
If humans didn't ever react with extreme violence when afraid or didn't behave aggressively when it was in their interest, we would not have wars and the atrocities that go with them.
There are two ways to end a war permanently, either by diplomacy or by one side absolutely crushing the other in a way that they have no way to come back from.
The latter is what most often happens because diplomacy can only work If all parties in a war are not so driven by an emotional need get what they want (or need) that they cannot talk to each other. If they could talk to each other and make concessions, they would probably have done so before they went to all out war with each other
So I do understand what Israel is doing but by the same token, it is absolutely right that people outside of that immediate circle of emotions keep calling for better solutions than all out destruction of one side. It is essential that leaders in war are held to account in some way and thst history judges thenlm, otherwise even baser instincts take over. .If we just stand by and say it is OK for Israel to do what it is doing, then we really are lost and they will stop even what they ARE doing to mitigate civilian deaths
Terrible things happen in war but if the people who do those things are not condemned then what hope does the human race have ?
War ia terrible and a price is paid by everyone, If you make decisions that lead to the deaths of many children and innocent civilians during war, no matter how justified you think that is in the circumstances, you should pay a price too. One that means you are condemned by the world for the things you did or decisions you made
That is my view and why I do condemn the Israeli leadership for some of their actions. Otherwise their overriding emotion of fear for their vulnerable position will take over completely and emboldened them to be even more aggressive in their defence of themselves
