 Greek analysts and politicians have expressed concerns that overseas observers tend to overlook or not to understand the severity of the perceived territorial threat and tend to misunderstand the conflict as a trivial issue over a name.The concerns are further reinforced by the fact that extremist ethnic Macedonian nationalists of the "United Macedonia" movement have expressed irredentist claims to what they refer to as "Aegean Macedonia" (in Greece), "Pirin Macedonia" (in Bulgaria), "Mala Prespa and Golo Brdo" (in Albania), and "Gora and Prohor Pchinski" (in Serbia).Greek Macedonians, Bulgarians, Albanians, and Serbs form the overwhelming majority of the population of each part of the region respectively.
