Greese occupied Northen Epirus,but Entente forsed Greese to leave albanian territories. In this timeline they rejected them and annexed NE. Constantine I hoped, that CP would help them. But German empire had many problems in two front war. Italy with support of Entente declared war on Greese. Bulgaria desided to join Italy instead of CP and attacked Greese. Italy annexed Albania and whole Epirus, Bulgaria got Greek Macedonia. Bulgaria still attacked Serbia, with support of Italy, but they didn't declare war on other Entente members. Without support of Italy and Greese Serbia surrendered. Bulgaria got Macedonia, A-H got Sanjak and Montenegro and Metohia was given to Italy. After that both Bulgaria and Italy became neutral and stopped helping CP. Entente desided not to declare war on them, because it could make winning war much harder. But Bulgaria still wanted to return Dobruja. Thats why Romania also remained neutral. Now there is only German empire, A-H and Ottoman vs Russia, Britain and France. Is this scenario realistic? And who would win WW1 in this timeline?
