In REALITY WW2 was WON because an evil, vicious dictator (3 of them actually) was defeated and stopped from taking over the continent.
I think this is what Tez means:
The total estimated human loss of life caused by World War II was roughly 72 million people. The civilian toll was around 47 million, including 20 million deaths due to war related famine and disease. The military toll was about 25 million, including the deaths of about 4 million prisoners of war in captivity. The
Allies lost approximately 61 million people, and the
Axis powers lost 11 million.
Look carefully at those numbers, 47 million CIVILIAN casualties, That is less then .01% the civilian casualties suffered due to 9/11. If going to war meant that the US would suffer millions of civilian casualties, have not just a couple of building destroyed, but huge pieces of its infrastructure, and that the bombs would not only be dropping on the other side of the world, but in US cities, would overthrowing Sudam, on charges that proved false, have been worth going to war? Not to mention that victory had almost 6x the casualties on the winning side compared to the losing side.
US "war" history is very different then it is in other countries. Some of your people like to tease France as "surrender monkies" and what not, but ignore the history. The US came in at the end, but over WW1 and WW2, as well as the time in between France probably did as much, if not more then the US to fight against Germany. They also suffered occupation, something the US has never been on the receiving end of, just the giving end. I imagine that would give them a very different perspective on the US occupation of Iraq.
Remember that in both World wars while Europe was fighting, and cities being destroyed the US was selling stuff to them for a good chunk of it, and staying out of the fighting. But no US cities where bombed, no US territory was occupied, and the battle was already turning by the time the US got involved, and when they did it was in Europe and Japan, not Washington or New York.
So when she says no one wins, remember that for a lot of other countries, war meant your own cities getting leveled, massive civilian, not just military casualties, homes destroyed, workplaces destroyed, etc. And that was if you "won." Hard to call yourself the "winner" there IMO.
