I think you're fundamentally misunderstanding this thing IMO, it has little or nothing to do with either corruption or even treason. It's got everything to do with mismanagement and policy. And the debt isn't part of the issue, it's a sign of a crisis that has already happened and forced us to take on bailouts in the form of debt from multi-lateral lenders. Any government could have stepped in to power in 2018, best of intentions etc. They all would be here today with extra debt and the allegations you've made, doesn't matter who you might suppose it would have been, even if it was someone you yourself judge to be of good character.
When Nawaz Sharif prematurely ended the IMF program mid way through, Christine Lagarde clearly said there are 'structural problems which if not addressed will lead to a relapse'. The other 'achievement' of this traitor is getting Pakistan out of the gray list. During his time Pakistan had a healthy rating from Moody's etc.
Question: Credit rating companies such as Moody's were completely unaware of the 'structural problems' hinted by Christine Lagarde? They had no idea of the massive debt levels being piled up, which would be payable in a few years?
Question: What did we get by moving out of the grey list?
Answer: The ability to pile up massive debt, after which we were sent back to the grey list.
Nawaz Sharif gets the boot, and the traitor Bajwa does a conference in Karachi about the economy. The establishment knew full well what was going on, yet nothing was done because they had to uphold 'democratic values'.
As soon as Imran Khan comes in, all of a sudden everyone becomes aware of the huge Current Account Deficit. Along with that comes the FATF pressure.
It is evident to even a casual observer that the debt and the FATF grilling have been engineered. And we have seen how it has benefited the enemy: silence on Kashmir. And Imran Khan is the perfect face of this submission with his pacifist approach.
I can tell you on good authority that the final aim is the breakup of Pakistan into 4 different countries and of course de-nuclearization. Zardari, Nawaz, Bajwa, Imran they are all facilitators towards this final aim of their masters.
