The United States is far and away the Saudis' most important and pivotal ally. We almost single-handedly ensure their security and and diplomatic standing. Now, many believe the "side causing excessive suffering" in that conflict is actually the Houthis. I would be interested to know if you fall in that camp, while (it would seem) not feeling the same way about Hamas, as that would do a better job of making my point than I could ever do on my own.
