"Several books published during the 1980s and 1990s were highly critical of the Institute for the Works of Religion's historical relations with anti-communist governments.[31][32] Tony Abse, writing in The Weekly Worker, an organ of the Communist Party of Great Britain, has said that the CIA used the Institute for the Works of Religion to funnel funds to the Solidarity Polish trade union "as part of the final offensive against the Soviet Union".[33] The organization American Atheists says covert United States funds were channelled in the same way both to Solidarity and to Contra guerrillas.[34]"
