Most of the "terrorists" killed by drones are people killed within walking distance of where they were born, people with little or no education who have not the slightest interest in any foreign country. Look at Yemen, one of the most activ areas for drones. A person is a potential terrorist if they are in the majority. Or Pakistan where tribal people, full hillbilly, were dealt with well by Pakistan through education until the drone industry decided education, though extremely effective, was not appropriate.
