Didn't released documents after 1989 show that most of the West European communist parties took orders directly from Moscow/Stalin?
IIRC, it was a big shock that the reason the Italian communist party was so reasonable after WW II was because it was orders from Moscow. (Stalin wanted to split Europe in two.)
I remember that the Swedish communist party used to be staunch Stalinists until Moscow told them he was wrong. Is that where the different view of Socialism came from? :-)
(The Swedish communists (SKP/VPK/V) claim to have stopped taking orders in the 1960s and have been critics of Soviet since 1989.)
