Khan's paternal grandfather, Khan Faizullah Khan, was a contractor, and the British used him to build roads and the cantonmentareas in the district of Dera Ismail Khan and in present-day Waziristan.
Now, earlier in the war, a U.S. commander on the ground reached a temporary cease-fire with the MEK which he justified on the grounds that it enabled our forces to contain the MEK forces in cantonmentareas, while not having to fight against them or to actively disarm them.
