Yes, that is so, but not so with aid coming from the US; surely you can see that Hamas will control it through intimidation and murder and infiltration.
The USA doesn’t fly it in (Israel shut down the air space), and the USA doesn’t ship it to a Gaza port (Israel shut down the Gaza ports for shipping), and that leaves only “over land” - and Israel controls that. There’s nowhere else for it to go except through Israeli hands.
Egypt does control the Gaza-Egypt border, but they’ve shit that down, and I’ve never heard any reports of the USA shipping anything through Egypt, to Gaza.
