Unfortunately for them, IK was too ambitious and rebellious.
He started using the army's traditional rhetoric against them.
However, due to economic turmoil, IK became very popular right under the nose of the army.
This causes more difficulty in removing him for the army, than what they had faced with others.
Now, the army and IK are at loggerheads with each other. Essentially a good chunk of the population with a cult like following for IK, against the army which is a major political and economical force in its own right, but not power given by the people.
An immovable object vs. an unstoppable force.
Looks like IK will be the one who will be destroyed.
All other narratives (corruption, bribes, etc) are for plebs like us to debate. In the grand scheme of things, those don't matter to Pakistan, because the struggle is not over corruption, but power politics.
