As a result of his activism, this resolution has been proclaimed every year by each successive president. He also founded and chaired for many years the related National Captive Nations Committee, which advocated for the nations memorialized in the resolution. In September, 1960, Dobriansky testified before the House Un-American Activities Committee on the role of Soviet premier Nikita Khrushchev in crimes against the Ukrainian people perpetrated by his predecessor, Joseph Stalin, such as the Holodomor. In 1993, Congress authorized the NCNC to begin raising funds to build a Victims of Communism Memorial. To this end, Dobriansky helped create the Victims of Communism Memorial Foundation, along with such notables as Lee Edwards, Grover Norquist, and Zbigniew Brzezinski. He served as the Foundation's first chairman. After many years of fundraising and advocacy, the Memorial was finally completed on June 12, 2007, less than a year before Dobriansky's death.
