You can't be serious. "67% of the Serbian people"?!? So, I guess the population of "Sandzak" is 6.7 million, right?
Do you even know what/where "Sandzak" is? It doesn't "border Serbia and Montenegro". It is a phantom region made up of 10 municipalities - 5 of which are in the Republic of Serbia and 5 in the Republic of Montenegro. Needless to say, neither the government in Podgoritsa, nor the one in Belgrade recognises it. Only the local muslim fundamentalists do.
As far as the Proposal for the new Constitution, you don't have to remind me of its contents - I am a member of the party that proposed it and I'm quite familiar with it. The Proposal is not the Constitution. I don't know where you got the idea that it was. Serbia has its Constitution, which was proclaimed in 1990 and which will be in force until a new one is drafted and adopted.
Why do you want to see more territory of Serbia eaten away anyway? Why support this movement in an area which you clearly know very little about (including its geography!)?
Yes it does.
