Accession of Macedonia to NATO
Following an agreement in June 2018 to rename the country the Republic of North Macedonia, NATO agreed to consider extending an invitation to the country to join at its summit on 11–12 July. On 11 July 2018, NATO invited Macedonia to begin membership talks, saying the country could join the organization once the naming issue was resolved. Formal accession talks began on 18 October 2018. Greece is expected to be the first NATO member state to ratify Macedonia’s NATO accession protocol.
Nuclear umbrella
NATO was formed early in the Cold War and, from the beginning, assumed American nuclear power as a major component of defense of Western Europe from possible Soviet invasion. Most non-Communist European states joined the alliance, although some (Ireland, Switzerland, Austria, Sweden, Finland) instead maintained an official policy of neutrality. Sweden and Switzerland considered developing their own nuclear weapons but abandoned the idea.
