You have a really strange way of deciding who won a war. Most people would consider those &quot;vague political goals&quot; the whole point of going to war, and the people killed undesirable casualties. But if USA really did go to war just for the sake of killing people, I guess they have indeed been pretty victorious. Much like Germans in WW2. I mean, they might have failed to accomplish whatever vague political goals Hitler had in mind, but they definitely killed a lot more people than they lost.
