Richard Israel can not resist Hamas without endangering the civilians all around them.
Because Hamas commits the crime of not evacuating them from around their positions does not mean they must be allowed to continue their other crime of indiscriminate attacks on civilians.
The law was not intended as an aid to terrorism but to reduce suffering in war.

Steve, re the casualty figures.
They prove that Israel is not killing indiscriminately.
Children and females are under-represented, all males are over-represented, and young men very over-represented.

That anomaly requires explanation.
The most likely would be that Hamas is lying about the status of its casualties.
Have you another?
