Is Serbia OK to give up it's cradle?

During the last 100 years Serbia moved her ''cradle'' depending from her territorial aspirations. Serbia's ''cradle'' was first in Kosovo, then it moved in Macedonia, recently they moved it in the northern Kosovo and it's just about the time to place it where is the real cradle of Serbia as we know them today (if we leave behind the fact that their real cradle is behind Ural) and that is Shumadija in Central Serbia, where by the way should be the border between neighboring countries: Kosovo, Serbia and Bullgaria.
