New and smaller provinces, with french (semi-presidential) system would be good for Pakistan I believe. We Pakistanis deserve to directly elect our president with more than 50% majority, instead of imposed dickheads like Zardari, Musharraf, etc..
Westminster system that we have in Pakistan is more of a fraud than democracy IMO.
Creation of new provinces is a sensitive issue, especially the division of Sindh. Punjab and Balochistan each should be divided in three provinces-- Punjab into "Punjab, Waseb (Saraiki speaking areas of Punjab) and Bahawalpur (former princely state of Bahawalpur should be restored as a province)" -- Balochistan into "Bolan (Pakhtun areas of Balochistan, British Balochistan), Makran (former princely states of Kharan and Makran) and Kalat (former princely states of Kalat and Las Bela).
Chitral should be taken away from KPK and merged with GB and should be given full provincial status with a new name, karakoram (or even Balawaristan (which means high landers in local language), personally I don't see any problem with this name, unlike some others) -- Hindko speaking and Hazarewal areas should also be separated from KPK and should be give separate provincial status with the name "Hazara" -- FATA should be merged with the rest of Pakhtun majority areas of KPK to form a new province of "Khyber".
Division of Sindh is sensitive issue, I really don't know what to say -- I think Sindh should also be divided into two -- former princely state of Khairpur and any areas west (towards Balochistan) and north (towards Punjab) of it should be merged with it to form a new province in north of Sindh and named "Sukkur" -- and the remaining area in the south Sindh should be another province with the name "Hyderabad".
Azad Jammu and Kashmir should also adopt the french system of governance and should be given the SAR (special administrative region) status under Pakistan supervision, with their own directly elected president and parliament -- with a provision in Pakistan constitution that final status of Azad J&K is to be determined after the Kashmir dispute settlement with india, in accordance with the wishes of people of Azad Jammu and Kashmir, whether they want to remain as a part of Pakistan or be an independent country.
