The narcotics revenue source is only one of three sources, says Defense Sec Gates. The other two are funds generated locally from the Pashtun minority in Pakistan, and funds generated from outside sources like people in Saudi Arabia and Kuwait. A 2006 World Bank report says the hawala system- an informal money transfer system using a network of money brokers with little oversight- "carries out the majority of the country's cash payments and transfers." Of the local sources, its only now that the Pakistan government is making a serious effort to freeze these bank accounts traced to the Taliban. The CIA says it has identified the charities and organizations that send money, but it is not clear if these sources have been suspended. The implications of this is that the war could be sustained by the Taliban even if the opium crop was destroyed, or smuggling routes and labs were destroyed. Gates points out that the very same external funding channels for sending money by wealthy Muslims that the US supported in the 1980's to help Muslim militants expel the Russians may still be open today. His comment that "it would't surprise me if some of those channels were still open today," suggests that even the Defense Dept does not know how these channels operate because of their extreme secrecy. In a way this shows how the war and the people that the US supported have come back to hurt the US, just as the people on the Pakistani side find that the people they supported in the Afghan and tribal areas and the Taliban organization they created is now coming back to hurt Pakistan. What makes it deeply disconcerting is that as Gates points out, there is so little time before the patience of the American public wears out with rising casualties. And on the Pakistani side there is so little time also because the war is spreading to Pakistani cities.
