Thank you for your opinion (stated as a fact, I'll add) that Israel doesn't occupy Gaza. Can you please state your source for this belief?
To state why I believe Israel is occupying Gaza, I'll point out that Israel’s continued status as an occupying power has been affirmed repeatedly by the United Nations, the International Court of Justice, the International Committee of the Red Cross, and human rights groups. Do you believe all of these entities are incorrect?
What is your source to justify your claim (stated as a fact) that Hamas is diverting supplies and then selling them? Here [1] is a recent article in the NYT this week quoting two unnamed Israeli military officials saying Israel has found no proof of this claim despite Israeli officials repeatedly stating otherwise, and that the UN had been largely successful (via UNRWA) in feeding the Gazan population.
