salaam,

While I understand your frustration with insecurity and killings....the afghan government will not be making the best use of their resources "going after peshawar" or pakistan. I am a believer in diplomatic relations in solving issues. The borders are so porous that if someone really wanted to enter and cause problems they would go about doing it and nothing would stop them. For the US or any other foreign occupier entering the region trying to tackle and grill suspects of "mischievous" behavior, it is all a shame and more than half of the time innocent people get hurt (either physically, verbally, or emotionally). Pakistan, needs to better secure their own security forces and contain their masses in their own country. Afghanistan has the important task at the moment of building up infrastructure: sewage, roads, basic necessities are needed. The southeastern border of afghanistan yields more of a problem, but the issue is too multi-faceted and complex to discuss in one comment. The U.S. has no interest in re-controlling the region bc at this point Afghanistan has shown its alliance with the U.S. and have concentrated their resources in Iraq. So to conclude, the Afghan government should not "go after peshawar and pakistan", meanwhile diplomatic relations should prevail in which case Pakistan better controls their populace.
