A forgotten uprising? East Germany 1953

[lethargic_man]

The BBC published an article the other day, "The six key moments of the Cold War relived" (for the benefits of those who couldn't remember it). Under the Soviet invasion of Hungary in 1956, it quotes a former communist supporter from London:

"My family saw the Soviet Union as the first country in which the working class had broken through and taken power. The invasion came as a tremendous shock. There were families and friendship groups divided by it. My father continued to believe that the Soviet Union's actions were correct. Others, like my mother, were more critical. It took me two decades longer to realise that the Soviet Union wasn't a socialist country after all because you can't have socialism without democracy."

It's well known how communist supporters in the West were shocked by the Soviet action then, and in Prague in 1968; it's only recently that I discovered that the whole phenomenon had happened before, in East Germany, in 1953. How did that uprising become so completely forgotten from the western consciousness (or at any rate, that part of it outside Germany)?
