Who are the allies of Serbia?
In WWI the allied forces (Britain, France, and later on America and Italy) were all allied with Serbia against the Austro-Hungarians and the Germans.
In the middle ages, the Byzantine Empire was the Serbian Empire's friend. When Serbia was occupied by the Ottomans, Austria, Poland and Venice helped Serbia. During the first Balkan War, Bulgaria and Greece were allies. During the 2nd Balkan War, Serbia allied with Greece. During the WWI, besides those already listed, Serbia also allied with Russia, traditional friend to Serbia. During WWII, Serbian allies included the UK, Russia, the United States, France, and other anti-fascist countries. After WWII Serbia was part of Yugoslavia, a non-allied country balanced between East and West. During 1990 Serbia did not have many friends, but now old allies are back, primarily Greece, France and the Russia . Curiously, Serbia has never had conflict with its two neighbors: Greece and Romania.
Even though some serbian politicians try to get Serbia inside Europian Union most of the common serbs blame the west for the desperate situation in whitch Serbia it is now.
Serbia isn't and never will be allies with NATO or america!!
