1. I am curious as to how he arrived at his position against nuclear weapons.

The article is not clear on this:

After the riots in 1953, Salam decided to leave Pakistan. He returned to Cambridge for a few years, before moving to Imperial College, London, where he helped set up the theoretical physics department. Despite the rejection from his home country he had suffered, he did not let Pakistan go, continuing to be involved in the country’s most prominent scientific projects. In 1961 he established Pakistan’s space programme while during the early 1970s, Salam was, controversially, involved in Pakistan’s efforts to build a nuclear weapon. But after the Prime Minister Zulfikar Ali Bhutto passed the law against the Ahmadiyya Muslims in 1974, Salam’s involvement with the country’s administration finally diminished. He went on to be outspoken against nuclear weapons.
