text_A: After witnessing the Indo-Pakistani War of 1971, which saw the unconditional surrender of Pakistan in 1971, Mahmood attended the winter seminar at Multan and delivered a speech on atomic science. On 20 January 1972, the President of Pakistan, Zulfikar Ali Bhutto, approved a crash atomic weapon program, under Munir Ahmad Khan, for the sake of "national survivor." Though, he continued his work at the KANUPP I engineering division.
text_B: If we assume that Mahmood himself is something of a national treasure for Pakistan, could we conclude from the passage that his ability to attend the winter seminar was one of the conditions of Pakistan's post-war surrender?
NO.
