SKA started publishing the magazine Revolt. SKA defended Stalin and criticized the new Soviet regime under Nikita Khrushchev. They criticized SKP for what they considered as "populism". But the group also expressed some criticism over the human rights situation within the Eastern Bloc.
In 1958, SKA tried to launch their own list of candidates for the municipal elections in Stockholm, but failed to get any seats. Persson died in 1960. After his death he group almost disappeared but continued to exist until 1967. SKA never played any role in Swedish politics, but the organizational experiences of the people who were active in SKA became important for the later generation of leftists, such as the KFML.
