The houthis just won this war and they still don't know why the US doesn't have free healthcare:
But my hope as the envoy for Yemen is that we can find diplomatic offramps to find ways to de-escalate and allow us to pull back eventually the designation and of course to end the military strikes on Houthis’ military capability. We favor a diplomatic solution. We know that there is no military solution, and in that commitment we are joined by all members of the P5 – Russia, China, France, the UK – united in this goal, and I think that’s very helpful for listeners to know that there’s a strong consensus in the international community and among key players to support the peace effort going forward.
