The US backs (either financially, politically, or militarily) 70% of the world's dictatorships -- many of which were placed into power after US-organised coups overthrew their democratically-elected leaders. Yemen has open-air slave markets, thanks to the US's bombings and destabilisation of the region.
The point is that "we are doing the humane thing" is not an argument that the US has legitimate access to anymore.
Also let's not forget that Saudi Arabia treats women as third-class citizens. Let's not pretend they're some paragon of virtue.
