I can't speak for France, Italy, and Spain, but the UK certainly are supporting it. A lot of the munitions dropped by Saudi Arabia on Yemen are of British origin. We also have some odd policies regarding SA - the recent transfer of ownership of the UK Football (Soccer) club Newcastle United is shrouded in mystery because the UK government granted special secrecy to the incoming Saudi owners. No, this is not fiction. There's a whole history of unpopular decisions regarding SA, and the wider UAE in general, in the UK. Many times trade (notably arms) sanctions have been called for and routinely ignored. E.g. when the tragic living and working (read: slave) conditions of much of the immigrant workforces were revealed.
