Any right thinking Pakistani should be very worried and concerned at the state of affairs right now. unfortunately, most internet warriors look for scape goats (India being the obvious one, and lately US, CIA/RAW/Mossad). All these may have contributed to Pakistan's decline, but they would have only exploited weaknesses that existed.
the question to be asked is, what are the contributing factors to those weaknesses, and what has Pakistan as a nation done to address them- to an outsider, the answer is that they have done precious little.
You only need to look east for inspiration (if you can shed your bias)- Not too long back, early 1990s I think, when I was studying economics at the Naitonal Univ. of singapore, we read about India facing a balance of payments crises and their Finance Minister pledging their gold reserves to the bank of england to tide over the crises. It seems that hte Indian political class took some sort of a pledge to never let that happen, and see where they are today- among the top 5 economies of the world, in a short span of two deades.
Pakistan can achieve the same- the fundamentals are all there, it just needs some tough decisions and teh werewithal to follow up on those decisions.
If for that democracy needs to be sacrificed and the country run by someone in the mould of lee Kwan Yew, so be it.
