Ahmed Rashid in the New York Review of Books:
To get to President Asif Ali Zardari's presidential palace in the heart of Islamabad for dinner is like running an obstacle course. Pakistan's once sleepy capital, full of restaurant-going bureaucrats and diplomats, is now littered with concrete barriers, blast walls, checkpoints, armed police, and soldiers; as a result of recent suicide bombings the city now resembles Baghdad or Kabul. At the first checkpoint, two miles from the palace, they have my name and my car's license number. There are seven more checkpoints to negotiate along the way.
Apart from traveling to the airport by helicopter to take trips abroad, the President stays inside the palace; he fears threats to his life by the Pakistani Taliban and al-Qaeda, who in December 2007 killed his wife, the charismatic Benazir Bhutto, then perhaps the country's only genuine national leader. Zardari's isolation has only added to his growing unpopularity, his indecisiveness, and the public feeling that he is out of touch. Even as most Pakistanis have concluded that the Taliban now pose the greatest threat to the Pakistani state since its creation, the president, the prime minister, and the army chief have, until recently, been in a state of denial of reality.
