Key point: Even though only India and Pakistan would be destroyed directly by nuclear weapons, the radiation and fallout would change the world. If enough weapons were used, it is very likely that the sun would be blocked out causing crop failures and mass starvation.
Sandwiched between Iran, China, India and Afghanistan, Pakistan lives in a complicated neighborhood with a variety of security issues. One of the nine known states known to have nuclear weapons, Pakistan’s nuclear arsenal and doctrine are continually evolving to match perceived threats. A nuclear power for decades, Pakistan is now attempting to construct a nuclear triad of its own, making its nuclear arsenal resilient and capable of devastating retaliatory strikes.
Pakistan’s nuclear program goes back to the 1950s, during the early days of its rivalry with India. President Zulfikar Ali Bhutto famously said in 1965, “If India builds the bomb, we will eat grass or leaves, even go hungry, but we will get one of our own.”
The program became a higher priority after the country’s 1971 defeat at the hands of India, which caused East Pakistan to break away and become Bangladesh. Experts believe the humiliating loss of territory, much more than reports that India was pursuing nuclear weapons, accelerated the Pakistani nuclear program. India tested its first bomb, codenamed “Smiling Buddha,” in May 1974, putting the subcontinent on the road to nuclearization.
Pakistan began the process of accumulating the necessary fuel for nuclear weapons, enriched uranium and plutonium. The country was particularly helped by one A. Q. Khan, a metallurgist working in the West who returned to his home country in 1975 with centrifuge designs and business contacts necessary to begin the enrichment process. Pakistan’s program was assisted by European countries and a clandestine equipment-acquisition program designed to do an end run on nonproliferation efforts. Outside countries eventually dropped out as the true purpose of the program became clear, but the clandestine effort continued.
