Why does beating an IDF soldier prove that he was the aggressor?

Arutz 7     Unbelievable footage has emerged showing an IDF soldier being beaten by Arab women and children in the village of Nabi Salah, Samaria

The video is already being seen by some as proof that the army is having its hands effectively tied, both by increasingly restrictive instructions on how to handle violent Palestinian rioters, as well as by insufficient backup from the political echelons against legal campaigns by leftist NGOs targeting IDF soldiers.

Nabi Salah is a particularly extreme Palestinian Arab village, which also hosts large number of far-left foreign activists. Arab and foreign "activists" regularly stage provocations and violent riots targeting both nearby Jewish villagers and IDF forces.

The video shows IDF soldiers responding to a riot on Friday, with one soldier detaining a juvenile rock-thrower. However, the situation quickly escalates as he is gradually surrounded by a crowd, largely consisting of screeching women and children.

As the soldier calls for backup in dispersing the crowd, some of the women and youths begin punching and hitting him. Despite being armed and trained in hand-to-hand combat, he clearly feels unable to respond.
