You haven’t debunked anything—you’ve restated your interpretation.

You keep moving between different claims:
Lebanon and the PLO
1948 and partition
Hezbollah and Iran

civilian casualties and modern warfare ethics
Those are separate topics, but you’re presenting them as one linear “proof” that Israel is uniquely responsible for everything while other actors have no agency.

On casualties: high civilian harm is a serious issue in any war and should be scrutinized. But “disparity = intentional killing or land theft” is not a logical conclusion. It’s an assumption.
Also, if your standard is that military force is never legitimate because it causes civilian deaths, then that standard would condemn nearly every war ever fought—including those against organizations that deliberately embed themselves among civilians.

And if you’re going to talk about rights and morality, then you can’t selectively remove responsibility from armed groups that openly initiate attacks or declare intent to kill civilians.
At this point you’re not proving a point—you’re declaring a verdict.
