U.S. forces are spread thin. They are engaging in most conflicts trying to act like mediators. I wonder if this will turn against them when a real conflict begins and they'll need weeks to move there.
The real conflict will begin when the Houthis engage in direct land war with the Saudis. And trust me, there is a strong chance of that happening very soon. Given the pathetic state of the Saudi Armed Forces (despite hundreds of billions of USD being spent every year on them), I am sure that the US Armed Forces will be compelled to intervene, to secure the Saudi oil output.
