I think IK is not here for Pakistan. I think there is a Pashtunistan in makings here. IK will be the PM for that as it'll be ethnic based. This is what it might turn out to be if this genius doesn't stop his violent and threat based politics.
Pakistani politics have a huge ethnic background. ANYONE can gather a few thousand people anywhere based on their ethnic make up. That's the main force behind IK and its unfortunately common in Pakistan. Country comes secondary from what I see in IK's politics.
You are right about the Civil War possibility....IK needs to realize that so far, others have been quiet as they want the system to run. But if you force them out when they have millions of more voters behind them; what will stop them from bringing their vote bank to streets? Nothing!! If IK destroys the system through a minority of voters trying to overrule the majority through violent tactics, others will bring people on streets and the Civil War will break out.
This trend would be like the creation of Taliban (here, violent voters so to speak). These violent based politics will hunt the Pakistani political system for many years to come (if not immediately stopped), and this could result in a Civil War, resulting in an ethnic breakup of Pakistan into a few pieces. Someone needs to stop this nonsense before everyone starts to bring their voters to streets to win "their power and land".
By the way, through counts available on Security Scanner / Walk Through gates that EVERYONE goes through, there were 32,000 people. Not hundreds of thousands (or Lakhs as you refer to it). Its amazing how 32 K people look on TV and impress their believers!
