Both the war in the Pacific and in Iraq the Americans didn't fight alone. Also British and Australians were involved in the Pacifique, in the Iraq war Poland as well.<quoted text>
Depends on what you think winning is, the war in the pacific and Iraq were undeniable in our favor. But honestly I'm not sure winning a war is possible anymore. There maybe ground gained and a temporary illusion of victory, but this fades away and back to conflict. This is partly due to human rights and partly to do with global communications. You just can't snuff something out anymore
and to win that would be the barbaric truth in winning war.
I think the question was about which wars the US won off its own last 100 years.
