Yes they will. The present regime, led by Zardari, who would want to implicate Zardari, for this crime when he was in jail or recovering from his mental disease abroad?
It wasnt the nation's ruler. It was a military dictator who forced himself on the people and was unpopular. I for one would love to see them implicate their own man in this lovely scandal. Just tell them it was Musharraf, and they'll be off our backs. Problem solved :)
My point is that very rarely are leaders of countries punished for actions of the country (the international criminal court only has jurisdiction over things like genocide etc). When it comes to actions committed by governments, it is countries that pay for the actions of an government, even one out of power. not individuals.
otherwise like I said, nothing would have been simpler for Germany but to blame it all on a dead dictator, and wash themselves of the consquences.
