text_A: Mahmood had witnessed his country's total surrender to India during the war of 1971, and afterwards, he delivered his speech about atomic science while in attendance at Multan's winter seminar. 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.
