"They can not get both", NATO Secretary-General Jens Stoltenberg told a news conference after the decision.
"We have made a decision to invite the government in Skopje to begin accession talks to join our alliance", the North Atlantic Treaty Organisation leaders said in their Summit communiqué. It still faces several hurdles - including constitutional changes and a public referendum in Macedonia - before it becomes final.
Greek Prime Minister Alexis Tsipras, right and his Macedonian counterpart Zoran Zaev, raise their hands during a signing agreement for Macedonia's new name in the village of Psarades, on June 17, 2018.
That is because Athens has always been upset FYR Macedonia is too similar to a region in northern Greece called Macedonia. Mirroring Macedonia, Greece's main opposition party, New Democracy, has also expressed its opposition to the name change, arguing that it does not put an end to potential claims by Skopje over Greek territory.
As reported by PressTV, NATO chief Jens Stoltenberg said that the door of NATO is open and will always remain open for Macedonia.
Numerous protests against the deal have drawn thousands of Greeks who oppose Macedonia using any form of the name.
Russia, NATO's most prominent rival, has bemoaned the possible addition of another alliance member.
He noted that the population of Macedonia must make your choice.
Sealed a month ago, the historical agreement between the two countries also satisfied the EU's most important pre-accession condition. According to a highly placed source within the Greek government that spoke to Ekathimerini, Greece has continually endeavored to get along with Russian Federation, but they feel it has been a one-sided effort.
Asked about the possibility of another member state, possibly the Netherlands or France, failing to ratify, the official said that it was strongly assumed that since all member countries agree that accession talks should start, they bore responsibility to ratify the agreement.
According to high-level Greek diplomatic sources, Athens is calling for the immediate expulsion of two personnel, including the Russian Embassy official Victor Yakovlev, and the expulsion of two more.
