Derived yes, but this will give israel access to everything US is doing, classified or not. All intelligence too, US doesnt share everything with israel right now, this is why Mossad keeps trying to implant various espionage devices on us personal and its embassy in israel too (they have been caught many times) but with this there will be no need,Isn't most of the israeli tech US derived anyway?. That said, the idea seems to be to make the embargoing/sanctioning/defunding by a future US congress not a risk anymore by providing funding and weapons directly through the US military.
us being part of the '5 eyes' means that israel will get all of their intelligence indirectly too.
And yep this is to make idf sanction proof.
