Again, you are giving gibberish numbers comparing between military rule and civilian rule.
Pakistan was not under sanctions in the 1980s or 2000s. Civilians Governments normally only inherit the country after military has violently destroyed it for 10-years at a time.
In December 2001, the Paris Club decided to reschedule Pakistan's external debt. Meaning, Pakistan will not need to make debt repayments for some of it's $12.5 billion loans for the next five years and for some of the loans until after 15 years. Here, see for yourself:
Pakistan - Paris Club Debt Rescheduled
13 December 2001

When the, PML-N Government came to power in 2013, it faced at least the following issues.
1) Pakistan's external debt was $53.4 billion as of June 2013.
2) Pakistan's Federal Budget was $35.5 billion as of 12 June 2013.
2) Pakistan was fighting a very costly war.
3) Pakistan was trying to recover from the 2008 Banking crises.
4) Pakistan was facing 18 hours of load-shedding, much of the industry was shut.
Considering the above, how exactly are you supposed to suddenly pay for debts that had not been paid for 15-years? How exactly are you expected to increase or at least sustain the export market without getting more loans for it, when your federal budget is so low? How exactly are you expected to fund military's self-proclaimed frontline donkey blunder?
The point being, where are you exactly supposed to get additional billions to fund 8 Chinese submarines, Russian helicopters, 50+ fighter aircraft, Chinese tanks, Project Azm, Chinese and Turkish warships, Space Centre, 2 LNG Terminals, Islamabad Inter. Airport, etc. as well as run the country at the same time?
Now imagine. Had the incompetent PTI Government was in power back then, India would've not only annexed Indian Occupied Kashmir but also invaded Azad Kashmir because all PTI can do is just moan and whine about CAD, Debt, Exports and Corona Rona Dona.
