The U.S. lost Vietnam because rural farmers thought U.S. troops were working for land lords. Land lords would take control of rural areas and start charging farmers rent after it was cleared of Viet Cong. There is a similar problem in Afghanistan: the Afghan government raises most of its revenues from sales and excise taxes, and doesn't tax land owners on property privately seized from rural residents. Since it doesn't tax land and has not centrally issued titles to rural residents, it doesn't have good records on land ownership and can't prevent private land seizures effectively.

These are not inevitable problems. Our politicians just don't understand the difference between land and capital and have undermined U.S. efforts to promote land reform in Asia after it worked so well in Japan.
