In 1850s and up to 1901, the British fought wars with Afghanistan to establish western boundaries of the British Empire. That is known to political science students as 'The Great Game', which has now been replaced by 'The New Great Game'. In the New Great Game, the British Empire has been replaced by USA while the other interested groups of the region include Russia, Iran and China, in short the SCO (Shanghai Corporation Organization). Pakistan is helping US with logistic support being provided through Karachi Port to Khyber Pass (75 % of total supply to Afghanistan) and through Balochistan Chaman to Kandhar (25%). The US is almost entirely dependent on Pakistan for its supplies. -DR KHURRUM SHAUKAT YUSAFZAI, Peshawar, via e-mail, March 31.
