The Saudis air strikes on Yemen are so brutal as to be considered by some as war crimes, will the US say anything or intervene as in Yugoslavia or just keep shipping the Saudi missiles and bombs to allow them to keep doing possible war crimes?

Yemen was supposedly an ally of the US, but I guess not as well as the Saudis (whom most of the 9/11 attackers came from), because Uncle Sam seems content to continue to ship them munitions so they can strike civilian targets ratchetting up the civilian death toll. Are the Saudis more strategic to the US now than Yemen? Is the US concern that they will make enemies of Yemen by not rebuking the Saudis but arming them so they can continue to inflict terror on Yemen? Because the US is backing the Saudis are other nations afraid to come to Yemen’s aid and defense?
