as far as i know israel, belarus, etc, aren't disqualified from playing in the world cup or the european championships. all sorts of nasty regimes play in the world cup, ivory coast has hardly been much better in the last few years with its fascist style goose stepping anti-muslim "youth movement" a few years back
there's an argument that including a team like north korea in the world cup will enable it to be more of a part of the world community and to open up a bit more in terms of the freedom of the press etc ...
anyway its just football innit?
