This operation have already targeted local groups first, and delayed any direct action against Mqm for 1 year, and even if they are acting against Mqm then its not to eliminate them but to clean them from criminal elements and baluch gangs or Sectarian groups don't have as much resources on ground to shutter off complete city or have K-2 , Pahri etc type of century makers, Not have nine zero type of headquarter that holds large amount of lethal weapons. as I told you on other thread that most of the city is in Mqm thug control. Mqm is ethnic based political party where G A Muhajir and Muhajir wazir alla kyun nahi kind of slogans are common, even after raid on Nine zero a common sentiment found among Mqm supporters is that Muhajiro ku phir se target kiya jaraha hey and its Mqm thugs that attacks liyari not Liyari that attack azizabad. Its Mqm thugs those are involved in sectarian target killings of both rival sectarian group, killing religious scholars, Professors etc. and trust me mate if any fair election in Karachi happens then it will expose Mqm's support reality. Anyone can win elections with guns.
