As an anti-war and principal Pakistan Movement activist, Amin is considered within Pakistan a patriot who worked to keep Pakistan united. He opposed the creation of Bangladesh during the Bangladesh Liberation War – but after the 25 March massacre, he devoted his position to reopening communication channels between the warring sides, curbing wartime crimes and repatriating Bengalis stranded in West Pakistan after the Bangladeshi liberation. In Bangladesh, he is considered a traitor who abandoned his own people.
