I think it all comes back to the Elite Powers of Europe wanting ALL the Middle Eastern Oil and Minerals.
Saudi Arabia has a lot of Mineral Wealth that not many people are aware of and Iran is chockers with Mineral Wealth.
Iran use to have an extensive Artisan Mining Industry but it started changing that when India and France invested close on US$10Billion in the Mining and Associated Mining Industries.
The start of the Indian and French investment was way back in the Sanction Years (so much for Sanctions if you are "In The Club").
I think Sanctions started back in 1979 and they have varied up and down and round abouts but didn't end until 2018 .................. depends on who was doing the sanctioning.
There's also the UNSC resolution 2231 (2015) that I haven't bothered to go into but it's still current so I believe.
Anyway, the whole thing is about thieving.
The "Powers That Be" want to pocket the whole damn lot of the Mineral and Oil Wealth of the Middle East and don't want to pay for any of it.
The UK, Germany and France are just part of the Machinery of the Deep State.
