Mr. Nawaz sherif let down both Vajpayee and Pakistan. He could have exposed the bluff of Musaraf by letting him surrender to Indian force(As done by Auib) instead of running to Washington. US wants a strong leader who can deliver american insterests at the same time keep majority of pakistanis in good humour. At least musharaf is able to keep up the first part to some extend. He can only act as a vijaykant of tamilnadu politics.
