There is a big qualitative difference between the conflicts in Europe and the wars waged by America. Wars in europe are nationalistic, vicious and leave deep scars even decades later on. It's fair to say we still haven't recovered from the scars of the 2 WWs and are still suspicious of each other. The US army is worldwide police. Their soldiers are basically heavily armed "policemen" who execute missions in exotic countries. That's why hollywood sees war as fun, technical an inhuman.
