Next time, if you want to know whether Karzai is speaking for himself or someone else, just watch his left cheek. It tics during lip service. The other day when he threatened Pakistan, the tic was a ball dancing like a ballerina on his left cheek. It was amusing to watch his pretentious courage while he tried to intimidate his nuclear neighbours. This comes from a man who through out his rule has failed to control Taliban in the centre of Kabul where his palace stands. -DR GHAYUR AYUB, London, UK, via e-mail, June 16.
