It’s pretty clear they’ve lost a lot of their footsoldiers in Karachi.
It’s why the target killings have almost stopped, alongside a large decrease in general crime and the fact they can no longer shut Karachi down like they have done in the past.
Have they still got thugs they can call on? Of course. They are so deeply ingrained in society getting them all is going to take more time. However the crux of them have been killed/caught/captured or are no doubt definitely in the sights of intelligence agencies. If they still had the ability to cause chaos like they did in the past, we wouldn’t be just hearing stupid threats like we do from their traitorous workers, we’d be seeing it in the streets.
