The Houthi strategy isn't an economic strategy, it's a "hope the US isn't willing to kill us" strategy.
Yemen's already in famine: https://en.m.wikipedia.org/wiki/Famine_in_Yemen_(2016%E2%80%.... The drones are supplied by Iran.
Is there some intrinsic right that the rocket-firers are defending that warrants treating them as other than aggressors in this situation?
Why do you call it genocide? Surely if you shoot at ships in international waters, and it is not defence, then you're bringing whatever acts of defence follow on your own head. Acts of defence seem impossible to class as genocide (but I'd like to hear arguments to the contrary if you have them).
Regaeding the latter, yes, for bow I think doing nothing militarily is exactly what is needed.
Never in my wildest dream would i think that the Houthis would be one doing the first modern blockade of a strait. I always expected the US to do the first modern block in the Malacca strait, when China is forced to do a Armed reunification with Taiwan.
