In WW2, yes, but you didn't save the world from some big nasty evil in WW1, Germany and Austro-Hungary wasn't the bad guys, noone where. In fact you only joined in when it was almost over and both sides had bled themselves to a stalemate in the trenches. Please don't try to take sole credit for this, instead I recommend you read up on it, it's quite an interesting albeit disturbing part of our history that is way too often overshadowed by the war that followed.
Note, my country was neutral, but I'm biased towards Germany. (they had spiky helmets)
