The death of Nicola Calipari sis the US's fault. yes.
It won't be the fault of the Brits, of the French of the Chinese.... Assume your acts. (here, your means USA

)
What kind of behavior ?
As I said, The Us amry is a professional army, maybe not the first in quality, but really good. Except for some young soldiers training, but that's not the point here.
As a professional and #1 world army, the US army should have a better behavior when it does a peace operation.
That's what i meant.
Sitarro, I disagree with you here.
She is not a dumb ass because she decided to go to Iraq.
She is a journalist, so, her job is to go in the sensible places of the wolrd to report the news.
If people follow your mind, and don't go in the troubles places, the news would be : "nothing new, everything is good in the best wolrd...."
A journalist HAVE TO be in the good place, at the good time. Iraq is the good place, now, because there are a lot of things here.
Would you critisize the war reporter, like the WWII journalists, or photographers, like Robert Cappa ?
She is responsible of her life, of course, but not of Nicola Calipari's one. But US soldiers are responsible of his death.
Merlin, sure, Iraq is more dangerous than USA - although... - .
But how can you explain the fact that the US troops kill more civilians that other army in peace operation ? Like the blue helmet in ex-Yugoslavja ?
If the same situation would happen between Iraqis troops shooting on US convoy, you'ld scream "it is scandalous !!!"
