Ahmed Rashid (the author of Taliban) writes a thoughtful--albeit with Tucker-like pessimisism--account of developments in Afhghanistan. His first paragraph is this:
"A recent border shootout between Pakistani and Afghan government troops in the Pashtun tribal belt has heightened already sharp tensions between the neighboring countries. In an April 22 meeting in Pakistan’s capital, Islamabad, Afghan President Hamid Karzai may confront Pakistani President Pervez Musharraf with claims that his country’s elite Interservices Intelligence (ISI) continues to secretly support the ousted Taliban militia. After an unprecedented two-day meeting of Afghanistan’s feuding military chiefs ended April 20 with a commitment to build a strong national army, Karzai faces another test: observers say he will try to persuade Musharraf to order his ISI agents to arrest Taliban leaders who are using Pakistan as a base."
