If you had actually just stated that it's bigger in the USA and Canada, I would have agreed. But because you know next to nothing about hockey in Europe, you decided to state that it's more worldwide. It's not, it's the other way around, and by a fairly large margin.You probably made that statement cause you think that an audience of 7 million Canadians and 1 million Americans makes a tournament "more worldwide" than an audience of 30 million Russians and one million Canadians. I can understand that you as an American might think that way, but that doesn't make it true.
Nothing in ice hockey is a world-wide event, but the WHC is more global than the WJC. Even the Olympic final of ice hockey is globally insignificant. People in Africa, South America, southern Europe and the vast majority of Asia don't care. Ice hockey is a marginal sport.
