As far as I'm concerned, there is no such thing as "war atrocities". War itself is the atrocity. It's an ugly, hideous thing--but when you have to fight it, you have to do what is necessary to win, and to win it as quickly as possible, so as to end said atrocity as quickly as possible.
To call what he did a "war crime", and akin to "torture", is missing the point. Had the guard been allowed to live, and had he been aware of Bashir and Sarina, he would have given that information to his superiors--and the result would have been a diplomatic incident--which it was the entire point of the mission to avoid.
An ugly, hideous action? Perhaps. It's called war. And in war, ugly things have to be done, to avoid a greater "atrocity" in the future.
No such thing as 'war atrocities'?
Garbage.
Exactly this sort of thinking justified the bombing of cities during World War II, targeting civilians in order to undermine the economy of the enemy country.
All this in order to win the war - I mean 'end the war as soon as possible', of course.
And, of course, because, morally, there is no difference between killing civilians and soldiers, in battle, during war - you see, any action during war is immoral.
If you really think that defending your country by fighting - and killing - enemy soldiers and indiscriminately killing civilians are pretty much the same thing, at about the same moral level - then I have nothing more to discuss with you.
Funny...I don't recall your "discussing" anything with me, before this post....
But while we're at it--I said nothing about "indiscriminately" killing civilians. Note my constant explanations about why targeting schools and hospitals was inefficient and ineffective.
As for Hiroshima...the alternative involved far more lives being lost--on both sides--and the war being prolonged indefinitely.
