The Houthis are unlikely to stop any of the war crimes they were already committing before the genocide started, and appeasing terrorists by giving them what they want works approximately 0% of the time.
Note: I am not defending any genocide here - I'm only emphasizing how deeply stupid it is to think that appeasing the Houthis will lead to positive outcomes.
How does that have anything to do the current crisis? Also the whole "we don't negotiate with terrorists" thing is basically propaganda meant to make the US look good rather than an actual successful political strategy, setting aside the idea of who is and isn't a terrorist given that it seems to be "does the US like them? Yes/no". I'd sooner call Saudi Arabia, their puppet government and the US terrorists for their genocide from 2016 to 2022 among other things; there's a reason the US bombing weddings is a meme.
Also I'm not sure which part of the file you want me to read; I searched "war crimes" and didn't get anything.
