Thank you for your interest. The MQM is a terrorist organization created by Zia to counter the power of the PPP back in the 80s. The leader of the party, an ex-cab driver from Chicago is a convicted murderer and fled the country in 1992 and runs the party like his personal mafia from abroad. The MQM engaged the Pakistan army in the mid nineties, though a hero called General Babur managed to break their back to some extent. They ally themselves with pretty much whoever is in power, yet claiming they stand against fuedalism (biggest joke ever). They have sponsored alot of ethnic based terrorism and envisioned the state of Jinnahpur which never came into existence thanks to Babur. They enjoyed some stints into power by selling out to the dictator Musharraf recently but in the end showed their true colors by playing a khoon ki holi on may 12th 2007 when they attacked innocent civilian protesters standing up for the restoration of a free judiciary in Pakistan. They collect bhatta (extortion money) and force people to vote for them in Karachi as well. Right now they are allied, ofcourse, with the ruling party and are trying to instigate an ethnic war against the Pakhtuns of Karachi in the guise of Talibanization.
Thanks for the information. I too remember a friend of mine migrating to Pakistan, on his return he used to boast about being a member of MQM, and how much power he has gained after migrating. This is in mid or early eighties.
