nothing will happen for sure.... you can`t ignore the reality.. without military Operation nothing will happen... because PPP will provide the save path to it`s Gangs War... and During Military Operation MQM`s Governor will provide the save path to it`s target killer...
Kan yaha sy pakro ya waha sy baat ek hi hai... You need to appoint the neutral Governor (an ex-military officer) except Ishara-ul-Eibaad and do the full and final Operation with Neutral Government and if not then You will see that Federal Government have to declare the military operation in Karachi in future and it`s 100% true prediction
