Perhaps your background is telling - you don't have a real 'home', hence you don't feel strongly about protecting it. I mean if things really hit the fan in Australia, you could go to Germany, or vice-versa. (Incidentally I have a similar background mix to you - lived in 3 different countries & have different citizenships and am writing this from Portugal, so know where you are coming from ;)

Most people are not like you. They have a home country that they care strongly about and want it protected. If that means killing some terrorists in a desert, so be it. And if a few people in said desert end up getting killed by mistake (and they tend to give benefit of the doubt to the drone operator) - that's war. Perhaps they shouldn't be hanging out near the terrorists.

My point is not to say whether this view is right or wrong - but to explain that the 'majority' who support the drone strikes understand what is going on and are ok with it.
