It's not "aid." It's fiscal transfer to vassal states (though 75% of it really goes to US corporations' pockets - aid isn't dollars but vouchers to spend on US products at 4x the market price) within the US empire. Just ask any non-voting subject of the empire.
BTW in numbers it's $4B/year - $3B to US firms, $1B to Israel. Our GDP is about $400B. Would we buy our independence for $1B per year, if the US was selling/if the world worked that way? You bet!
(And don't get me wrong, it might be the best empire to be the vassal of for Israel which is too small to be independent. Just let's call it what it is.)
