Radicalization??

No. Yes, there were a few attacks on aid trucks. People who saw aid going to those who were holding Israeli hostages. You realize Israel was under no legal obligation to permit the aid? Don't chant "Geneva", it only requires allowing aid to non-combatants. When there is even a reasonable threat of diversion to military purpose the obligation goes away--and there was not only a reasonable threat, but the vast majority was being diverted.

The only appreciable Geneva violation that Israel engaged in is not sending notice of suspected misuse of civilian things--but this is of no actual importance as the rule exists to avoid mistakes. It wasn't written with a situation where civilian cover was used to the greatest extent possible. For them to have simply said "everything is being misused" would have been a pretty good approximation of the truth.
