Point is he doesn't want to destabilise Karachi for his own political gain or he would have visited Karachi ages ago. He doesn't want to be another Chief Justice who went on with the visit and MQM started attacking all the areas/people who supported him resulting in chaos and death.
My dear!
I used to admire Imran Khan and still do, but his policy regarding KArachi and MQM is same as that of PML N in 90s. He was just creating MEdia Hype. Although i do criticise MQM workers for mass anti Imran Khan campaign in Karachi , but i do also criticise Imran Khan for his words against MQM.
Specially when everybody knows that MQM Haqiqi was a pure millitant organisation who had occupied Malir and Shah faisal area by force, where even after winning the elections MQM MNAs and MPAs werent allowed to enter. (MNA cant even his own constituency, ) it was only in 2002 that their infrastructure was disabled, and other parties MQM, JI, and PPP were ablw to enter there physically.
Imran khan has been trying to reviive that party, and its on record. (MQM Haqiqi consisted of two groups, Amir Khan and Afaaq, both millitants, even with such a control over malir, they couldnt win any National assembly seats from Malir)
Other thing is that what ever you or any body else may say, Karachi is full of MQM supporters, and after 12 May (within 1 month), if Imran Khan would have visited Karachi he would have endagered his own life. anyways, after May 2007, Imran Khan only chose to visit KArachi after th gap of one year, when the political situation in Karachi was again critical, that shows that he was just interested in gaining political Mileage there.
Apart from this I admire Imran Khan very much, i dont know why he doesnt do his homework on Karachi before speaking on the topic, because clearly his sources are not from Karachi, and I know that he is not delibratly doing this, as he is not the one who plays dirty politics, but the fact is that he has played dirty politics in case of Karachi and MQM.
Like for example, I havent heard a word of support from PTI for works of CDGK, and when a certain newly constructed bridge collapsed in Karachi, Imran Khan was quick to criticise CDGK and say that CDGK is involved in corruption that y it happened. While the fact was that , the bridge was part of Northern Bypass, which was the project of Federal Govt and was carried out by federal Agency (FWO or NWO or something like that i forgot the exact name, but the organisation was federal), and CDGK nor Sindh Govt had anything to do with its implementation.
So my advice for him would be, to stop cashing on Anti MQM hysteria, (created by PML N in 90s) as he does not need this, he is fully capable of emerging without any dirty politics.
