Saudi Arabia did commit war crimes but it wasn’t genocidal. The only intent was to support their preferred faction in Yemen and prevent Iran from having an ally on its border.
Saudi Arabia is big and diverse and so is Yemen. But the two countries’ people are more alike than different and intermarry more than they do with any other country.
I am not denying or excusing what happened. As far as I know though the ICC or ICJ never ruled it was a genocide.
I'm afraid to get my hopes up only for them to be crushed. I will celebrate only once the breakdown has been confirmed and proven irreversible.
