bodach yes numerical literal made there meant 16,000 not 160,000 apologise but as Dalrymple says in his masterly book on the Afghan War 1839-62 :'The parallels between the two invasions were not just anecdotal, they were substantive. The same group rivalries and the same battles were fought out in the same places 170 years later under the guise of new banners, new beliefs and new political orchestrators. The same cities were occupied by troops speaking the same languages, and they were attacked again from the same high passes. In both cases, the invaders thought they could walk in, perform regime change, and be out in a couple of years.'
Till the time of Tony Blair invading Afghanistan was infamous for its folly and what is more an indelible mark had been made there convinced that the US were trying to do what the British had done. Hillary Clinton was aware of this not sure the others were.
