Mark Rose has updated the Archaeology Magazine Online Features section with an article which consideres what can be done, if anything, to save Pakistan's heritage from further damage. This article most usefully puts the situation into its political context and goes on to consider what the results of the political upheavels have been:
The turmoil in Pakistan, especially the situation in Swat, has scholars concerned about the safety of the country's artistic and archaeological heritage. Relatively peaceful until recently, Swat was a tourist resort with spectacular mountain scenery. It also has a rich cultural heritage, especially Ghandaran art and Buddhist monuments. Adriana Proser, John H. Foster Curator of Traditional Asian Art, at the Asia Society in New York explains, "This area of what is today northern Pakistan was along a major route of the Silk Road. Gandhara was one of the major sites of the Kushan period (first through third centuries). The art of the Gandhara area is extremely important because it shows the impact of Hellenistic and Roman influence ushered in through the conquests of Alexander the Great. The stylistic impact of Gandharan Buddhist art traveled vast space and time, reaching places as far away China, Korea, and Japan. The Gandhara region became part of the Sasanian Empire (224-642), which preceded Islamic rule in Persia, and consequently the arts of the region also influenced artistic developments in the Middle East."
The consequences of prolonged political infighting in Pakistan, leaving Taliban-like militants unchecked may have dire consequences for this heritage. On Monday, October 8, dynamite was used to obliterate the face of a of 23-foot-high seventh-century seated Buddha carved into a rock face near the village of Jehanabad in the Swat Valley. The attack on the Buddha, according to police chief Mohammad Iqbal in an AFP story, "appears to be the work of the local militants who condemn these relics as being un-Islamic. It looks more like a symbolic attack to embarrass the government internationally."
