The IMF is nothing more than a negotiating and an influential tool at the hands of the west. These chaps will do as told by their stake holders, and the stakes largely rest with the west, with the US in the lead with over 16% share holding, and Britain, Germany, France, Australia and a few more from Europe together making it well over 50%.
The IMF was not even ready to negotiate when the PPP government was there and Hillary was the Sect of State, but with the PML-N in Pakistan and John Kerry as the Sect of State, the deal happened over night. We can be absolutely certain the deal didn't just go through based on some sound economics that the PML-N will bring to table, but was a part of larger give and take in Afghanistan with thorough KSA backing. For one, the so called "peace pipeline", that was to origin from Iran, has come to a halt, also the US has just recently issued a statement that the first right to buy of mil equipment from Afghanistan will rest with Pakistan, says a lot on the direction this relationship is headed.
Further, this year's Pakistan's proposed budget is well over 50b usd, and they have significant commitments coming from the US, the PRC and the KSA of their financial support to this budget. Pakistan, for as long as one can remember, has allocated anywhere between 27% to 35% of its budget to defence under various heads, even under the most dire of the situations, so there is no way they will shelve that, ever!
One also needs to figure in soft loans, grants, write offs, and my sense is, if Pakistan is ready to play the US' game in Afghanistan over the next 5years without much duplicity, a significant portion of the IMF loan will be written off.
