The sooner Pakistan becomes a "Secular" nation the faster she will walk in the path of progress. Islamic Republic as a governing idea has failed miserably both in Pakistan and Iran. There is no reason why Pakistan can not do what already has started by India. You got the brains (West Asia first nuclear power and first to start space activity when everyone else was sleep in this area).
As for Iran my prediction is that within the next decade Iran will again be a "secular " nation but more important this time around Iran will also be a non- muslim nation with a small muslim minority population.
Hopefully the mullah crowd in Iran would also disappear from Iranian landscape after them appearing in the Iranian history only 500 years ago . Mullahs have always played a negative and destructive role in Iranian history. They were always considered "parasitic" entity and tools of foreign nations to impose their will on Iran. Invented 500 years ago by the Safavid shahs to control the population and later used by British to keep Iranian population from Progress..
