UAV strikes are simply dropping a bomb on a bad guy and the pilot just happens to be far away from the platform.
What is the difference between a fighter pilot flying an F-15E over-head the tgt-area and dropping a JDAM, or a fighter pilot flying an F-15E miles and miles away and dropping a SDB-II (glides VERY FAR) or a fighter pilot sitting in an UAV "cockpit" (easy-chair) in Nevada (with better resolution screens than found in the cockpit overhead the tgt) and dropping a JDAM .
No difference. . .and who gives a darn about terrorists and due process while in a combat zone.
Define “ combat zone”
Is it anywhere a president or prime minister decided it is?
Or just in countries with governments too weak or too unpopular to the West , like Syria and Yemen, to gain any concerns about unilateral military acts in ther countries?
