I personally have a different views on this question, one for Greeks and one for Macedonians.
There is no closer nation to Serbs then Greeks, more then 1.1 million Serbs or cca. 13% of our population visited Greek coastline this summer, or 70% of all tourists from Serbia.
As a European I belong to Greco-Roman civilization and as a Serb I belong to Byzantian commonwealth which is practicaly Greek Empire which civilized south and eastern Slavs. Thats truth and everyone who denies it have inferiority complex towards Greeks.
So, Macedonians are Slavic nation that steals Greek history, small nation on periphery of human progress which try to steal, forefathers of all human progress since Aristotel till Ottoman occupation.
On the other hand, Serbia need stable southern border and for Macedonians ( and huge majority of Macedonians are good hearted people) it would be great to enter NATO to save itself from Albanian tribes that get stucked in 3th century.
So it is win win situation for both Macedonians and Greeks. Macedonia will stop to steal glorious Greek history, and for exchange it will became stable country that will have to civilize Albanian tribes with they primitive culture ( blood revenge, incest, selling daughters to wealty Serbs, Bulgarians, Greeks, Turks..., prostitute and drug powerhouse of the Europe).
I want to avoid being banned again for Albanian thessis in my last sentence and for that I will provide sources for my accusations.
