Did you know that America recently carried out drone strikes in Waziristan and Yemen?
Don't worry if your answer is 'no' - because as John Oliver points out, you were unlikely to find out unless you were watching the Iranian government's English-language TV channel.
Check out this clip from 'Last Week Tonight', in which Oliver investigates how and why America uses its drones - including the loopholes that allow it to deploy them even if the threat isn't 'imminent' and the targets are innocent civilians. It's fascinating, funny, important and terrifying in equal measure.
