didn't the us use some stealthy bombers to wreck some houthis? also i think the us does not want to stir shit up too much with the houthis because saudis barely got the civil war to wind down and this could make the conflict flare up again.  it's a delicate balance in that area, as saudis don't want to piss iran off too much either and get their oil installations bombed again. saudis are rich but they don't have much of an army.
