The trial is still going on. Clark (the presidential candidate and former commander of NATO forces in Europe, and in their fight against Milosevic) will be testifying against him early this week.
Yes he is still defending himself. He is making quite a bit of headway by all accounts now he has adjusted to the ways of the tribunal and is not making speeches and irritating the presiding judge.I can't think we are looking at a 100% win for him but he's making a fight of it.
With any luck it'll go to a retrial; well, you have to look after lawyers; they might become an endangered species if not kept going !
Yes, he still is defending himself. His trial began in february, and so far nearly 300 witnesses have testified, so yes, it has been a rather long one.
