If Nawaz and Zardari are the most corrupt individuals in Pakistan then we should also accept Altaf Kalia to be the biggest criminal in the history of Pakistan.
If Altaf Kalia's supporter start a thread about corruption of Zardai and Nawaz, then its like "The pot calling the kettle black".
Yes, Imran did propose Musharraf for president but none of us knew that Musharraf will turn out to be such an 'A-hole' in the future. I can put this action of Imran under political immaturity but we can not say he is a munafiq or he did this due to some ill intention in his mind. I also think he has learned a lot from his past experience and he will make a good Leader for Pakistan. Currently, if we look at the political landscape of Pakistan we only have crooks, criminals and munafiqs and Imran does not fit into any of these categories.
