Israel and Egypt are always pointed to as recipients of greatest US aid. But that is only because the US military that is stationed in South Korea, Japan, and a bunch of other countries is not counted as aid. And all that military is very expensive, like in the tens of billions or maybe even hundreds. I don't know how much it costs to maintain an aircraft carrier fleet to protect the Arabs from the Persians.
And on a similar note, when comparing overall spending on the military, the perception of the size of the US military is inflated because in China and many other countries there's a draft, so they pay their soldiers next to nothing while the US has to pay theirs a prevailing wage, which is somewhere around the highest in the world.
