edit: Oh, and soldiers don't burn thousands of dollars of revenue every hour they spend in the field, and recruit way fewer terrorists than the drones do.
Evidence suggests that the trauma of living under drones causes anti-American resentment and aids in the recruitment for violent extremism. According to a former State Department official, for every drone strike, the U.S. generates roughly forty to sixty new enemies. Such long term damage is known as “blowback” – incidents that arise in later years as an unintended consequence of actions taken today.The cost per flight hour varies by type of drone. Predator and Reaper drones cost about $2,500-3,500 per flight hour; larger armed systems such as the military’s Global Hawk cost about 10 times as much: approximately $30,000 per flight hour.
