I'm sure it's a small deal, but the U.S. needs Saudi Arabia a lot more than it values the life of a single human being. I'd expect any of its leaders to rebuke the Saudis, but not to the point of losing then as an ally. That's logical, even if immoral. Putting the greater good above the good of individuals is the job of the state in a nutshell.

What is reprehensible here is Trump had not even gone so far as to offer a rebuke or a wrist slap here. That's unfortunate since it tells the Saudis they can continue to get away with this in the future.
