That was not "yesterday." The Saudis had plenty of time to move their armed forces to protect themselves if necessary. Who is there on their soil attacking them NOW? Maybe I'm missing something. If they're being attacked by drones and missiles there is little our troops on Saudi soil can do. Besides remember Trump's comment above about those endless tribal wars.
Of course we can't get between the Kurds and Turkey. Trump can't benefit by the Kurds. He already is by Turkey. There's the Trump towers there for Trump to consider plus his future plans for Turkey and RU. This is a conflict of interest for a president and you can't deny that. Trump has to dance when Turkey or RU sings... and Trump danced and will keep dancing.
You seem to only be getting one side of what's going on.
