Typical defeatist mindset................
Little over ten years ago there were seven countries whose central banks were not under control of international bankers. Since then three have fallen, Afghanistan, Iraq and Libya. Did you notice that within weeks the Libyan rebels established their own central bank. Having said this, let me assure you if Pakistan tries to be smart and start accepting PKR instead USD, economic sanctions will cut the value of PKR in half before you can realize what hit you, like it's happening to Iran Riyal.
Asif Ameer, what you are saying is all true but it is not doable in todays world. In todays world what Adnan_apml is saying is more true, Saudi Arabia will never accept credit from any other country other than USD for oil, because they are the gurantor of keeping the USD as world reserve currency. So in other words any country that has any power to change the status of USD is Saudi Arabia. Thats just my opinion.
