Serbia declares independence from itself

Serbia is now the sixth former Yugoslav republic to declare independence. The only probem, though, is that they have nobody left to be independent from!

Slovenia left (with no war), Croatia left (with a big war), Bosnia-Herzgovina left (with a bigger war), Macedonia left (with a smaller war), and just a few days ago Montenegro left (with no war). They all declared independence from Belgrade.

So what were the legislators in Belgrade thinking when they declared independence? Oh, I know, they had to lower the S-M Federation flag and raise the Serbian banner in its place. But did they really have to go through the formal declaration? It seems a waste of time.
