The actual violent civilian caused by coalition forces are estimated to be around 15,000 in Iraq and 10,000 in Afghanistan - over a period of 20y and populations around 25x that of Gaza.
Everyone knows that Israel essentially went on a rampage of revenge, which you basically seem to agree with given your explanation for the destruction (i.e. not military necessity while protecting civilian lives).
There are more than 300k civilian deaths attributed to the period.
The Gaza figures include military deaths, civilian deaths including killed by Hamas, and even natural deaths, it is more comparable to the 1 million number and due to its use of natural deaths it is even overcounted compared to the 9/11 number, (I am deliberately ignoring the 4+ million indirect deaths number quoted on brown)
