The US has a habit of setting bad precedents these days and that is especially true of drone assassinations. Now every country will want a drone fleet, and we have given them all the excuses they need to employ them to "kill terrorists". Of course, like us, they will be the ones who decide what a terrorist is. UK courts just decided that journalists should not be considered terrorists, indicating that we are in a world of hurt when that question even comes up.
How can the US complain when other countries deploy drones to "kill terrorists"? It can be done much cheaper than our drone program, and with much less high-end technology. You just need a video camera on an RCA big enough to carry an explosive payload. What goes around comes around. But then again, I am sure that is the whole point. The US wants instability, or we wouldn't be forcing regime change all over the place. I can't imagine that the government hasn't figured out that regime change leads to conflict, civil war and refugee crises. In fact, it happens every time.
