Your turn.
You should bring that up with all 6 republican leaders, including Milosevic, who agreed that Croatia did have the right at the EU meeting in 1991. Take it up with Belgrade.
I asked you far more questions than that. Don’t bother though, it is clear you are hopelessly biased on the subject and it is not worth the time to argue with you.
