My answer is a dual one. They shouldn't been allowed in the first place because they're not even in Europe. But maybe they're included because they're a Western-style nation on a close enough patch of Earth?

Otherwise, we, Mexico and Canada demand we can participate.
I answered "Yes" because they're already allowed to participate. The festival is already heavily politicized and so nations protesting one another is a foregone conclusion. Let them opt out or whatever.
