Generally DFFG avoided taking a public stand on non-Vietnam/Indochina-related issues. It did however condemn the Soviet military intervention in Czechoslovakia in 1968. Gradually DFFG became more outspoken in their anti-Soviet positions, which in turn caused conflicts within the movement. In 1974 the author Sara Lidman publicly protested against the anti-Soviet postures of DFFG. The 1975 congress of DFFG (held after the Vietnamese victory) removed the slogan "Fight U.S. imperialism", with the rationale than a movement that solely condemned U.S. imperialism would become a tool of 'Soviet social imperialism'.
