He has alleged that Ghulam Azam, a former leader of Jamaat e Islami at the time of the liberation war, had played an important role in the mass killings of the 1971 conflict, as had Jamaat as a group. He has also said that the Razakars were founded by the Jamaat e Islami leader, "Maulana" A.K.M. Yusuf. Kabir has supported efforts by the Awami League-led government, which won a two-thirds majority in the Parliament in December 2008, to establish an International Crimes Tribunal in 2009 to prosecute war crimes. The first trials were completed in early 2013, with three men convicted who have been prominent in Jamaat since the liberation war, which the party opposed. Afterwards he called for a ban on the Jamaat-e-Islami party. Ghulam Azam was also convicted by the International Crimes Tribunal.
