I thought everyone here was smart enough to realise nothing happens for one reason alone. And sorry to say this, Morgeruat, but Wikipedia is comparable to a children's book when it comes to definitions and explanations. You hardly have the entire picture when you read about World Wars 1 and 2 there.
Every heard of the Willy-Nicky telegrams? Did you know that Switzerland actually fought an aerial war with Germany in 1940?
Not to be offensive here, but sometimes the simplicity with which people pose reasons and causality amaze me.
And yes, I'm a history student
