And they should do so.
However.... Talking to an Italian friend back during the group play stage, she said that the Italian team is one of the few things that brings all Italians together. I think that's true of France, Germany, England etc and their national teams. And I think that is because of multiculturism and shame of their heritages and pasts (not like Germany can celebrate Nazism and conquering, however briefly, almost all of Europe).
Of course I totally agree with your amplification on my point. Perhaps the day will come with all the multiculturalism and shame heaped on our country by the Left that we once again find that same nationalistic pride felt by the World Cup nations.
Hopefully the unintended consequences of OweBowMao are just that.
