Collective Punishment is a war crime (Red Cross)

[Beastly Boy]

20. The obvious purpose of this post is to accuse Israel of imposing collective punishment. Not so fast.

The definition given talks of "types of sanctions, harassment or administrative action taken against a group in retaliation for an act committed by an individual/s who are considered to form part of the group."

Who does Israel sanction? Hamas.
Who does Israel harass? Hamas.
Who is the group being retaliated against? Hamas.
Which individuals does Israel act against that do not belong to the group called Hamas?... Crickets.

Does Israel have the right to sanction, harass, administer retaliatory actions against Hamas? Absolutely.
Who is responsible for the well being of protected people in such circumstance? Hamas.

This is what Articles 28 and 29 of the fourth Geneva Conventions say:

ART. 28. — The presence of a protected person may not be used
to render certain points or areas immune from military operations.

ART. 29. — The Party to the conflict in whose hands protected
persons may be, is responsible for the treatment accorded to them
by its agents, irrespective of any individual responsibility which may
be incurred

But it's easy enough to imply guilt by association when you only tell the part of the story that fits your narrative.
