One thing that will not be decided on in Chicago today is expanding NATO membership. Four countries have been on the short-list since 2008: Macedonia, Georgia, Montenegro and Bosnia and the Chicago Summit’s outcome document is full of supportive words for their eventual membership. But for now, NATO expansion is on hold.

These countries have different things holding up their full membership. For Macedonia the issue is very simple: Greece has effectively vetoed Macedonia’s NATO membership over a dispute between Athens and Skopje over the name of the country of Macedonia.
