The latest entrant into the NATO alliance, Montenegro, underscores both the absurdity of this archaic cold war relic and the dangers it poses to the United States.

Yes, Montenegro is a real country, kind of: with a little over 600,000 citizens, and around 5,000 square miles, it has an army of under 2,000 soldiers and sailors. During the medieval era it was divided into warring clans who were unified only by their fierce opposition to Ottoman rule: the boundaries, and the rulers who presided over what became a duchy, were fluid, like the boundaries of neighboring Balkan states whose instability and propensity for conflict gave rise to the phrase "balkanization" as a synonym for volatility. Once the ancient bastion of Serbian nationalism – the country was bombed by the US during the Kosovo war – Montenegro's demographics underwent a transformation and now the country is pretty evenly split between Serbs and other nationalities: the country's politics, too, are polarized, with the pro-Serb pro-Russian opposition parties and the pro-EU pro-NATO parties almost evenly matched, although the latter have tenuous control of the government at present.
