When Mohammed bin Salman, sixth and favourite son of Saudi Arabia’s King Salman, launched Operation Decisive Storm against the Houthis in Yemen in 2015 he expected the war to be won in a matter of weeks.

(This is a picture of skeleton thin children starving in Yemen. You'll have to use your imagination or search the internet, I don't have the stomach for it right now.)

(Note: I've got a little 6 month old grandson visiting for the holiday. When I saw the picture of the starving child in Yemen, I saw his eyes looking at me. Angry? You bet.)
