There are no civilians. Plant a weapon next to him and he's an insurgent.

But .. this happens in every war. It is just so that there are media which are able to inform people as it happens, unlike in former times where a few sparse military reports would sweep all under the carpet of a reason of state.
But certainly, from Abu Ghraib, Guantanamo, pi**ing on Taliban corpses to drones killing civilians as "collateral damage", this is indeed not the way "to win hearts", or build up a country. But maybe the latter is not the point.
To compare the death of a US citizen to an Afghani or Iraqi and then saying "those scumbags do not count" is not only inhuman, racist and xenophobic, but plain dumb.
