When someone tells you that the 80's protests in communist Poland were inspired by the US, pro-capitalist or any other similar bullshit, just have a look at this 1980 list of 21 Interfactory Strike Committee postulates.
@kravietz To be completely fair, anything that was anti-Soviet, regardless of how otherwise socialist it might have been, would have had Western support.
The fallacy here is that there was any such thing as "the West". Each country had different policy towards Eastern Bloc, and within each of these countries there were countless movements that either supported or condemned the anti-Soviet movements. For example in France you had organisations that both supported Solidarity (Polish independent trade union), and also die-hard communists (L'Humanite) that would approve of any Soviet decision, regardless of how stupid it was.
The latter case ("against PLO") is invented for the sake of exemplification as Moscow created and then consistently supported PLO. Abu Nidal actually had an office in Warsaw from where he operated through all 80's.
