There has not been any modern warfare fought on US soil, could that be a reason that the people cant really understand the true horror of civilian casualties?
Same can be said of the UK although to a lesser extent , they did get the shit bombed out of them during WWII.
I'm aware of the huge importantce of the US during the war, but whilst their young men were fighting in Europe, they didnt have to worry about their wife and kids getting blown up.

This is not a bash America comment just a statement of fact.
