And you're actually raising a good point here: Only US citizens get to vote on the US federal government, which controls FAA, yet many countries indirectly rely on the FAA as the primary regulator for Boeing, as far as I understand.
Maybe the regulators of a few large industrial nations or the EU have the size/staffing/funding and leverage necessary to make a difference (and that's still a few steps removed from the FAA!). Others (Ethiopa and Indonesia come to mind) are effectively at the mercy of the FAA.
