a) If PPP will not obey the orders of court then Prime Minister will be imprisoned on orders of court but soon after that he will be pardoned by President (using special presidential powers).
b) If we do not open the gates for NATO? hmmmmmm
...'no' is never said in foreign affairs dealing. If we really do not want to open gates for NATO then we should demand few things in return which USA can never give. Our demands should be duty free trade with USA, necular deal with USA, USA should sell us drones, huge taxes on NATO goods transport, USA should only use Pakistan Railway for goods transport within the territory of Pakistan etc
c) Yes PPP should resign voluntarily but we can not expect this sort of kindness with the nation from PPP.
