The Gas Wars are continuing. Starting well during the time of USSR, when the USA tried to stop the supply of the Russian gas to Europe by the means of sanctions and provocations, through the Ukrainian gas machinations, when Ukraine was used as a patsy to sabotage and undermine Russian supplier reputation, while at the same time blackmailing Russia for cheap under-market-priced gas, which I wrote about in a 2014 article The Third Gas War: EU and US must pay for their “successes” in Ukraine.
Now the USA are trying to sabotage Nord Stream 2 by blackmailing Germany. This follows the successful blackmailing and sabotage of Bulgaria, which stopped the construction of the South Stream and depriving Bulgaria of about $700.000.000 and $800.000.000 per year over a span of 50 years – USA and EU successfully stole from Bulgaria about $37.500.000.000
And before that, USA/NATO invaded and bombed Yugoslavia, bombing into oblivion the gas refinery in the Serbian town of Pacevo in 1999.
All this recent, and not so recent, history is very well chronicled in the new English-subtitled documentary from Vesti: “The Great Gas Game”
UPDATE 2022: Since YouTube applied the “freedom of speech” principle and removed all speech that does not conform to the American directive on freedom, i.e. all Russian channels, including the one from the VGTRK that hosted the documentary, I re-uploaded a backup copy, which I happened to have, to Odysee.
