Lashkar Gah is a city built by the US in the 1950's. It is north of the Nowa district where I was in Afghanistan. It was modeled after the Tennessee Valley Authority. Scientists and teachers came and taught the American children who lived in the model houses and the Afghans. There were 27 schools and education was thriving. The valley was being cultivated and there were big plans for agriculture.
The Afghan people were and still are very poor. While they welcomed the American's with their Pastun traditions there was little in common. It was given up and mostly destroyed with the Soviet Invasion. But been rebuilt and now considered the Las Vegas of Afghanistan.
