With drones, the question is how long before the dozens of states with the aircraft can arm and then operate a weaponized version. “Pretty much every nation has gone down the pathway of, ‘This is science fiction; we don’t want this stuff,’ to, ‘OK, we want them, but we’ll just use them for surveillance,’ to, ‘Hmm, they’re really useful when you see the bad guy and can do something about it, so we’ll arm them,’ ” Singer said. He listed the countries that have gone that route: the United States, Britain, Italy, Germany, China. “Consistently, nations have gone down the pathway of first only surveillance and then arming.”

It’s the creeping use, combined with perceptions of citizens’ inability to affect government behavior that, combined, arguably are provoking resistance to drones in Canada and the US.
