You know I somehow doubt this considering hamas didn’t mount a permanent offensive of any kind
They literally raided for less than a day and than ran back with hostages. No way they’re just sitting on stockpiles of fuel and resources if it couldn’t be immediately used, and they were aware that everything was going to get intensely bombed anyway.
Yeah they probably do have stockpiles, but nothing substantial.
Even the article mentions the released hostage who saw them eating the same one meal a day of bread and cheese.
