Can we also say only a brainless person will pardon someone who has crimes against the nation (not just one person)? May be 2:00AM calls have something to do with all this.
Most likely, there was external pressure to have benazir become part of the equation and the only way that was going to happen was by having her and her husband pardoned. Countries face and feel external pressure. With the situation pakistan has been it becomes more precarious. I doubt that any of our regime's in near future will be going against such pressure. Questions would be whether Musharraf pardoned them only for the sake of bolstering his own grip on power or were there bigger concerns and issues which necessitated it. Maybe we will find out later at some point in time. We do know that her return was brokered and orchestrated by US and personally supported by Condi.
