note1: Why Albania is part of Kavkaz Region and not Mediterranean Region? I can see many (sport) connection between Albanians and Greeks and also connection between Georgian, (Kavkaz) Russians and Greeks so that's why Greece and Albania are part of Kavkaz region. I know Bulgaria should be there too but there was not place. Sorry guys.
note2: Many people don't understand why Israel is part of Europe in all kind of sports. There is big reason. Can you imagine (football, basketball...) qualifier match between Israel and Iran (Syria)? Israeli judokas have sometimes problem fight against Egyptian, Syrian etc. judokas.
