"We take the view that the popular forces in Poland are capable of solving their problems to their advantage. It is inadmissible that strikes take place in socialist society. The strikes in socialist society are directed against socialism and are not useful to either the workers on strike or the working class in general. These demonstrations are directed against peace, security, and detente."
January 1, 1970
