There were already plenty in Musharraf's years from 1999-2007: Less corruption, less waste, less focus on using religion in daily discourse, political stability, making an honorable peace with India. Yes, his govt got help after 9/11 but such help but I don't think $20-30 billion 'aid' over so many years, of that aid a chunk was for military support, was the most important factor in Pakistan's relative properity under Musharraf. Also, Pakistan can learn a lot from Bangladesh.
If it would come to that, Pakistan can more than survive following some kind of North Korean version of the 'Juche' philosophy: There is a lot of internal industries and agriculture and service base. There is a huge domestic economy and potential trade with Iran, China and countries to the north and west of Pakistan. There is a huge diaspora which can support Pakistan. It is not a country like Greece or Sri Lanka who were/are over-reliant on tourism.
I certainly believe Pakistan can get out of its trouble under the 'right' leadership. I also think Pakistan CAN get out of the reliance on the West in no longer than medium time frame if Pakistan decides to. Really decides to.
