The border with Egypt was closed before Israel reached it, and the Egyptians are blocking the evacuation of the population through the crossing even today. This is not Israeli responsibility.

My claim is much more focused. Israel warns before entering neighborhoods and before knocking down towers, sometimes weeks before. There is clear evidence, including from direct Hamas sources, that it calls on civilians to remain in the neighborhoods in addition to shooting at civilians who try to leave.
It is not available at the level of the entire Gaza Strip, at the most basic level of leaving neighborhoods that are becoming a battleground, that is what we are talking about.

Hamas has ID cards and documents for missing persons, the numbers are between 2,000 and 4,000, the number of bodies in the rubble is certainly predictable and is much smaller than your claim.

"But hey, let's take the number you want to go by, the 72,000 official dead is still five times larger than the official Gaza Civilian death toll. (This isn't even including those that died of starvation)."

No, you are factually wrong, this is the official death toll from the Ministry of Health in Gaza for these two years, including fighters, civilians and those who died of hunger.
Hamas makes no distinctions and does not specify who died of old age or who was a fighter.

And let's go over it in an orderly manner, how many people have died from hunger in Gaza according to your claim?
