The source of the food scarcity being discussed started on Oct 7th though when the government of Gaza chose to kill over 1000 people, maim/injure/torture/rape thousands more, and kidnap many (including the approx. 6 year old girl they posted videos on the internet of themselves kidnapping from her house, they were so proud they posted video of kidnapping a little girl from her home). That all happened starting Oct 7th.
