there was no need to target MQM, and in fact in Lahore, it was not to target Mian brothers either, it was just that they felt the heat and made it look as if its against them.
the Karachi Jalsa was for peaceful Karachi, despite the fact that posters, banners were torn apart and even vandalism was shown by burning the car in parking stand, PTI kept its head cool...
once in power, I am sure PTI would deweaponize Karachi, and reign of terror will die with it. and Karachi will have a peaceful political life.
as for alliance, if MQM agrees to certain points, its a fair deal for reconciliation,
and the biggest of all, after decades, Karachi Participated in Pakistan Politics, #Change
P.S and you must appreciate that whatever maybe the reasons, Altaf did welcome a positive change in Karachi, unlike Mian brothers...
political competitiveness is a positive sign...
