> It'a not a decision made by US airports, the US requires every person who lands on US soil to clear US customs even if that person's final destination is outside the US (ie. the US doesn't allow sterile transit).

Is it true that they must clear customs _in addition to_ passport/immigration control? If so that is indeed unusual.

Yes, you have to claim your bags, pass thru customs and then check them on to your next flight
