Absolute nonsense, from the first sentence to the last.OK, time for the truth
Massacres and rapes are a necessary reality in any war. Some of them occur for legitimate military reasons (i. e. the civilian in question is suspected of aiding the enemy in some way), and some of them occur simply because there's no one "policing" the war.
It's totally naive to believe that the incident described here is an exception to the rule. In war, these massacres are far more commonplace than the times they're actually exposed to global media coverage. It's reasonable to expect that US troops massacre civilians and rape kids every day, just as the Taliban or other competing Afghan factions do, simply because that's what happens in war, regardless of the parties involved.
The notion that this kind of thing is a rare occurrence is just more propoganda from uncle sam to appease the ignorant (childish) American public.
That being said, if one is unwilling to accept these massacres as a cost of a war, i. e. if one doesn't believe that the importance of the mission of the war outweighs these kinds of brutalities (rapes, massacres, tortures, corpse urinations), then the war should not be started, period.
Since the war in Afghanistan has no meaningful mission at all (except possibly to create a government that will allow American firms to mine and exploit Afghanistan's natural resources and labor), its benefits clearly do not out weight its brutal costs. Therefore, the war should be terminated.
Unfortunately, since the US is not a democracy, the American people have no say in that.
