Violence and disagrements on taxation between the provinces and central government are stressing Pakistan. The central bank governor has resigned, becasue the government has asked the central bank to print money to pay its bills. This is not good. His replacement is a professional banker, but he is an advocate of lower interest rates (focusing on growth not rising inflation). The markets dont like that either. Elections have to be help before Feb/March 2013. The politicians want to buy their victory in the way Musharaf did.
There are shortages in many things. Skills, finance, governance, electricity, gas and water. Against a backdrop of a poor economy, this is a dangerous cocktail.
The 18th amendment to the constitution has not been implemented well (provincial decentralisation) and this is leading to more friction. US/Pakistan relations have also deteriorated a lot, threatening USD 1.5bn of aid a year, some of it already being held back.
The real risk of a military coup is now very high.
