Russia is the world's third-largest oil producer, behind the U.S. and Saudi Arabia, and the world's largest exporter of crude to global markets. It is also a major producer and exporter of natural gas. So, it is impossible if EU prospect a Russian gas ban.
If EU not able to import gas from Russia, then the country stops, the economy stops, cannot heat the houses, cannot run the economy.
When they impose sanctions, then they have to make sure that those sanctions are hurting more those against whom they impose the sanctions than themselves.
I'll just leave this real picture of gas and oil production, and now you try to prove your statement
World ranking of countries by oil reserves.
Why stocks? Because this will show how small the share of Russia in its monopoly among the European corrupt countries dependent on Russia, financing the center of world terrorism in the Kremlin...! And the list objectively shows who will easily replace the supply of Russian oil ...
So the rating is:
1 Venezuela 302,300,000,000
2 Saudi Arabia 266,200,000,000
3 Canada 170,500,000,000
4 Iran 157,200,000,000
5 Iraq 148,800,000,000
6 Kuwait 101,500,000,000
7 UAE 97,800,000,000
8 Russia 80,000,000,000
9 Libya 48,360,000,000
10 Nigeria 37,450,000,000
... and where, Russia, on which the whole world depends on oil? )))) Say it's funny, does reality look against the background of propaganda?
