Funny how all of the quotes in this article take the assassination of human beings by flying robots, piloted by people hundreds or thousands of miles away, as perfectly fine. It's normalized as an accounting problem, how the dead are sorted and tallied.
Imagine for a moment that Iran sent a drone into America to "neutralize" a prominent politician or neocon in Washington D.C. who was advocating war against them. Using our logic, Iran would be perfectly justified in doing so. Of course, if such an assassination actually occurred, the consequences would be outrage and a massive attack on Iran.
So when you really look at it, you can see that the only reason drones are used like this at all, is because the countries they are used upon can't fight back. The United States is simply being a bully, stinging other, weaker kids on the playground with its new toy.
