Pakistan/Afghanistan, August 15: The Taliban is responsible to a great degree for the mess in which Afghanistan finds itself today. The volatility in the country is also a result of its neighbour Pakistan's backing of Taliban leaders. And as US-led NATO forces start leaving, the Karzai government is seeking reconciliation with the Afghan Taliban. Unfortunately, Pakistan's spy agencies, the ISI and Military Intelligence hold the key to Taliban leaders and are undermining any peace agreement between the Taliban and the Afghan government. The Taliban leaders living in Pakistan include Mullah Muhammed Omar, Hakimullah Mehsud and Mullah Mohammad Omar Akhund.
