Well the important thing is that these kids are not "brainwashed by UNRWA" into becoming Genocidal maniacs. Israel teaches their children to be peaceful functional and totally not Nazi-like adults.
It is really, physiologically sickening to weaponize children into taking out what, food? What can the same age children on the other side can do with, choke inncocent Israeli's to death?
This right here is how you create and raise monsters that can dehumanize someone that have been through the same heaviest dehumanization these childrens' own grandparents when through, to eventually make up the most moral army in the world.
