Well that is much easier said than done. The terrorism that you are so afraid of, is a greater threat to MY life. You may have heard of the spate of suicide bombings going on here in Islamabad.

Swooping in and shooting the hell out of a hill in balochistan is likely to set off protests and MORE suicide bombings here. WHy should Pakistan risk the health and wellbeing of its own citizens, why should it risk the lives of its population and why should it risk great internal instability for the US?

The point is that while Pakistan is in ally in the War on Terror, it is not a proxy state. Thus its priorities are NOT the same as the US's. For you the most important thing is to exact revenge on OBL & Co. FOr Pakistan the most important thing is to prevent suicide bombings. Actions such as the ones you propose are going to reduce the security of the Pakistani people.
Well i never was one to take offence at mere words.. But yeah its sort of like the N word. WE can say it but you can't.. Though i think that's just silly.
