Post Second WW & Bretton Woods; World Bank and IMF were created solely for the purpose of western hegemony. So, it's no wonder World Bank decided to pull a fast one with SHW government.

That's the primary reason of western ire. Younus+Hillary definitely pulled strings from behind. That's what beltway power-brokers do all the time.
