It’s a term that goes back to the cold war. There was a strike and the Soviet Union ended it violently by rolling tanks into the city. This put communists all over the world into a bit of a dilemma: on one hand was the working class making their opinion known (a communist value) and on the other the Soviet Union (the good guys).

It was British communists who coined the term “tankie” for those who defended the SUs actions to brand them as “fake communists” who are more interested in identity politics (the good guys did it, therefore it’s OK) than the plight of the working class.
