It's always made me wonder what the US would be like if we *had* suffered the kind of losses the rest of y'all did during the Great War. Would we have the same militant, might-makes-right attitude as today? Or would we be more cautious?

Good question - I've wondered that myself more than once. Although we didn't learn much from WW1 or else there wouldn't have been WW2. In fact, if US president Wilson had had his way with his League of Nations, and if the British and French politicians hadn't been so eager to punish Germany as hard as possible (Wilson was against this), it would have been interesting to find out what would've happened instead in Europe.
