Well, it is true that all problems started after election … and do not think that people who invests are idiots that they were investing in Pakistan until election (rather, until one of the biggest Liar in Pakistani politics, Ishaq Daar, made mess in press briefing with lies and propaganda). If people with money are closing their businesses, stop investing in the country, selling their assets and leaving Pakistan, this is all happening because of election results and incompetence of present government or their lack of interest towards well being of Pakistan.
Anyhow, since you love reading about mistakes of Musharraf and cause of present Pakistani problems due to Musharaff, then here it is: Musharraf mistakes started 8 years ago when Musharraf decided not to hang Nawaz, rather Musharraf accepted Nawaz begging for life and promissing to leave politics to do ‘Allah Allah’ in Saudi Arabia, not realising that when Nawaz says ‘Allah’, he means ‘pounds and dollars’. Musharraf mistakes further happened 6 years ago when Musharraf decided that Pakistan needs democracy (however sham) and thus had election 2002, and then another mistake followed 4 years ago when Musharraf thought that Zardari should get similar deal as Nawaz so he left Zardari as he left Nawaz, making Zardari leave for Dubai to do ‘Allah Allah’. Things became worse when Musharraf did another big mistake in 2007 when Musharraf tried to show decency and instead of giving 2 choices(resignation aur takhta) to corrupt CJ, Musharraf only suspended him and sent charges on him for investigation, resulting that corrupt Iftikhar starting bhangra on road with the help of corrupt politicians and corrupt lawyers. Musharraf made another big mistake in later 2007 of thinking that Pakistani politiicans are not animals but humans, would leave their greed and would learn from their mistakes so he gave them a clean slate with NRO (withdrawing all pre-Musharraf period cases … regarding corruption or whatever … of Nawaz, Zardari and other politicians) so that they can behave like human, stop destabilising the country and start working for the country, but unfortunately he was wrong. Then Musharraf made mistakes of letting these crooks run for election and get back into power. Further, Musharraf made mistake of letting these thugs scare investors away from Pakistan, resulting in ruining of the country and economy of the country, but Musharraf did not sacked the parliament, instead Musharraf resigned.
