The Taleban are reported to be within 70 miles of Pakistan's capital, Islamabad. It appears the Pakistan government is about to be somewhat inconvenienced and may even have to evacuate. The situation should be considered parlous.
Most likely the government would relocate to Karachi, which is in any event a bigger and more significant city, located 600 miles south down the Indus river valley. This would put them well outside the Taleban's area of influence and should preserve the regime for a while longer.
Look out for helicopters on the roof on a TV screen near you.
