U1 is an important key. Russia was not our friend. While I oppose picking a fight with Russia, Russia got in bed with Obama/Clinton with U1. Russia had to oppose Trump to cover up the U1 crimes.
Then there is the destination of the uranium. The only point that doesn't fit is that I don't think it would be in Russia's interest to spread nukes to more Arabs. They have their own problem with moslems. Perhaps they aren't worried about Persians (Iran) getting nukes however. One benefit is that a war involving Iran/SA would send oil to $200, which would help the Russia economy big time.
