While I think Neo 1's sentiments were a little rash, comparing WW2 with the current wars is in no way a like for like comparison. WW2 presented a situation that could only be overcome through co-operation and the outcome was in the interest of all allied countries, including America. Its a perfect example of how important co-operation is. This kind of unification is impossible to attain through means that abachler suggested.Now hold on a second. Isn't America being villianized now for being involved in a war it has "no business being in"? And you wanted them landing on the shores of France in the 1930s?
For example take the wars in Iraq and Afghanistan. The current American government wanted to go and start a war, most European countries were strongly opposed to this so Bush took the Abachler approach and created a confrontation by insisting that anyone who's not going to join the war is against them. By completely ignoring the opinion of the rest of the world while being caught up in the post 9/11 mob mentality America lost much of its credibility. Ultimately what the American government has managed to do over the last few years in increasingly isolate themselves, which ironically is what caused the downfall of the nazis.
Until recently Americans seem to have been oblivious as to how much the rest of the world opposed this aggressive attitude. When I was travelling in Australia in 2004 I met americans that pretended to be canadian because they were so fed up with all the grief that they would get about their governments actions. Personally I think its unfair to judge anyone on the actions of their nations government. Thankfully the american popular sentiment seems to be shifting tho.
