Drone strikes civillian kills Obama vs Trump.

Ok. Just a question from a Norwegian dude. I know Obama was trigger-happy with the drones...and I also know that Trump (who I support...just saying) use the birds. I have looked on the web for info about who is the most user of these machines and statistics on just witch of the prez that have caused most civilian damage in the years they have ruled. I have a feeling..but no facts..just going blind and confused ....with the info I find. So you US people...anyone who knows? I know its kind of an ugly morbid question but who of Obama and Trump uses drones the most and who does it best? (lowest civilian body-count). All the best from Norway and good luck in the coming election. :) I hope the post is getting attention....Please bump me around a little bit.
