I think you're deliberately failing to appreciate the relative importance different nations attach to the IIHF WHCs. Some nations care more; some care less. The IIHF has done a wonderful job for decades, through its own misconduct (Ahearne, Sabetzki, Dombrowski, Kompalla and a cast of hundreds more), of rendering its world championships illegitimate in the eyes of North Americans. Thus, you get too many North American players who come over because an agent tells them they have to.
Or they come over for a 3-week bender.
And plenty more who could come over decline to do so.
Biased officiating, subpar accommodations off the ice, an alien rulebook (remember now, Euros whine about having to play by the NHL rulebook for the World Cup, but don't see why it should be a hindrance for North American athletes to play by someone else's [often unevenly applied] rules) and no-name opponents who like to hack and whack all make it easy for North American-based NHL players to take a pass.
I think it's safe to say that, as European countries struggle to win the Olympics in the NHL era (3 of the last 4 have been won by the "wrong" country), we are undoubtedly going to see more and more posters like this one who emphasize the primacy of the world championships.
Here's one thing that has always fascinated me about some posters.
When an event is played on large ice, with European officials, following a European rulebook, in front of European fans, it is somehow a "legit" and "level" playing field. When an event is played in North America, following an NHL rulebook, using NHL officials, and in front of North American fans, it's illegitimate and "biased" and "unfair".
Any explanation why that might be?
I'll confess in advance that I'm someone who doesn't much value the IIHF's world championships because I do not value the IIHF - mostly because of its deceitful practices and checkered past.
