Macedonians will head to the polls this Sunday to vote on the historic Prespa agreement that could end a 27-year diplomatic impasse with Greece, which has refused to recognize the country's name since it declared independence in 1991. The agreement could also set the Balkan country on a long-desired path to NATO and EU accession.
Why it matters: For Balkan countries seeking NATO and EU membership, Macedonia’s success would signal that the door is open. By lighting a pathway to Euro-Atlantic integration, Washington and Brussels could also leverage a “yes” vote to promote democracy and stability in the region, while signaling to the Kremlin that its continued meddling won’t be tolerated. Either way, the referendum's outcome will have significant geopolitical implications for Europe and the U.S.
