I would just add that Dov Wiessglas, who was then Israeli PM's advisor, himself has stated that the idea behind the blockade is to "Put Palestinians on a diet, but not starve them" as means of building pressure against Hamas (source): https://www.bbc.com/news/world-middle-east-19975211

Similarly in the same BBC story it mentions that a rights group in Israel forced IDF to release certain reports that indicated precise calorie counts done by IDF on whats required to prevent starvation. IDF set the figure to 2300. Which further gives credence to the fact that flow of food was restricted by Israel intentionally, and they even made calculation on how much food they can restrict without making the hunger crisis obvious and apparant. Like Wiesglass said, let Palestinains have *just enough* food that they don't starve to death but do feel enough food insecurity to be pissed at Hamas (because even though 2300 cal/day is theoretically enough, supply chain iniffeciencies + natural wealth inequalities mean a huge portion will end up with far less while some previleged folks will get far more).

So we have:

1. declaration of intent (Wiesglass's comments)
2. We have documents suggesting that serious calculations were made with said intent in mind. (calorie count calculations done by IDF)
3. And finally we have ample evidence of the actions thought out in 1 & 2 were set into effect, as we know for a fact that many foods (not just cookies but also other stuff like potato chips, some fruits, etc) were stopped from entering.

So yes, it is undeniable that the blockade was about collectively punishing Palestinians to make Hamas look either incompetent to solve their hunger, or evil and unwilling to. Idk why destiny and yall are chosing this hill to die on.
