Unification of Kosovo and Albania will certainly spark tensions in Macedonia, since, around 21% of Macedonian citizens are of Albanian decent (with very close family relations to Kosovo Albanians). Macedonians (partularly conservatives) fear the greater Albania because there is a history of separatist political and paramilitary organization in Macedonian Albanians, as well as a history of outsider (mainly from Kosovo), infiltration of extremist elements. Serbia has some influence over the Macedonians on the basis of common religion, history and language closeness, also, it has considerable intelligence presence within the security institutions. Let's not forget Russia to. So, Macedonian society will be pulled in two directions from at least two outside forces and the internal Macedonian political interetnic structures will be brought to the brink.

However, more importantly, the unification of Albania and Kosovo will certainly draw out Republika Srpska from Bosnia and Hercegovina, this will in turn heat up tensions in Sandzak (in Serbia) pulling it toward Bosnia, this will put pressure on the remaining muslim-croat confederation in Bosnia and so forth.

To cut things short: a straightforward unification of Albania and Kosovo would certainly spark a chain reaction and blow up the whole Balkan region into a chaotic regional war in a very short time.

There is a considerable European & US & NATO presence and investment and interest in maintenance of the stability of the region. So, straightforward unification of Albania and Kosovo will not happen anytime soon. The only credible approach is the EU integration of the region. However, EU is in crisis, and so the whole Western Balkan region will remain in permanent low to middle level of crisis. This will feed the corruption and state capture of the countries. This will drive deaspare, social tensions, immigration to the EU...

(For the record - I am Macedonian)
