There's only one man really responsible for those events - Yahya Khan. Both he and his advisers were so drunk with power and corruption they'd even forgotten the honor of the army.
Zulfikar Ali BhuttoI felt certain uneasiness, a strange sensation, which had comic to a head. Every evening I went to Yahya to report that Mujib [Rahiman] and I weren't making any progress, and Yahya [Khan] showed no interest. He looked away or complained about the television or grumbled because he couldn't listen to his favorite songs - his records hadn't arrived from Rawalpindi.
Zulfikar Ali BhuttoYes, there are circumstances where a bloody suppression is justifiable and justified.
