Presidents of Afghanistan and Pakistan meet on common ground

The President of Afghanistan, Hamid Karzai, and his counterpart from Pakistan, Asif Ali Zardari, met in the Turkish capital Ankara yesterday. They agreed to increase military cooperation against Islamist extremists. It’s a significant step, because relations between Afghanistan and its neighbor Pakistan have been frosty after Afghanistan had accused Pakistan of not doing enough to prevent militants attacking from the Pakistani side of the border. The meeting came as the Commander of U.S. forces in the region, General David Petraeus, told a Senate hearing that the fight against the Taliban in Pakistan would continue because, as he put it, the Taliban pose a threat to Pakistan’s very existence.
