a nation not really used to dealing with conflict
I recall a conversation once with an american who described the 9-11 attacks as "the worst civilian death toll from any single event in the history of the world."
They were serious.
In all fairness he is an American, they tend to have a very... clean image of war and events to say it politely.
It is a well tailored illusion, but an illusion non-the-less.
So be nice, he doesn't know how many people died during any single bombing run in WW2, Vietnam, or even how many people die in traffic accidents in a year.
I find myself thinking that one of the reasons why the US as an entity seems to be less averse to wars, and the maintenance of the ability to fight large wars when compared to the mindset of generally conflict averse EU nations, is that wars it has been involved in in a truly modern sense of the word (lets say post WW1 for sake of argument) have been wars at a distance fought on territory far from home.
I personally think it is because Americans hold a highly unrealistic view of war and its costs and that this illusion is well taught and hammered into the popular mind. They still believe in this idea of the "Surgical War"...
You notice that in Vietnam the second Americans realized "Hey, people actually are dying in this war" they immediately wanted to stop it... but good luck finding any American who has anywhere close to an idea of how many civilian casualties there were in that war.
While Europe a place that has been devastated by war before... don't really hide that aspect.
