Abstract
Iran becomes a nuclear weapon state in immediate future or not is hard to predict forecasted, however, this study reveals the implications of a nuclear Iran for the Middle East in specific and the world at large. Unlike De Gaulle, a nuclear analyst who opined that the possibility of the states with nuclear weapons behaving illogically has been based on unfounded fear and blown out of proportion, the analysts belonging to other school of thought assume that if Iran gains nuclear status, it would enhance her influence on the Arab states that would increase rift between Shiite and Sunni states of the Persian Gulf, the signs are already visible. Some analysts also believe that in future, nuclear Iran would go to war in Middle East that probably would be nuclear, against the U.S. and Israel. None of these scenarios can be either accepted or rejected out-rightly. Even the accord between Iran and P-5 plus 1 does not provide clear direction as to how Iran would behave 10 years down the line if strict measures are taken by the U.S. and its allies. However, it is viewed that the situation for Pakistan as a result of a nuclear armed Iran might not be as grim as considered by some scholars. Pakistan and a nuclear Iran being the two neighbouring countries might continue to enjoy good brotherly relations.
