For the second time in as many months, Ukraine’s crisis threatens to spiral out of control, with the Ukrainian military now trying (mostly in vain) to secure several cities in the Russian-speaking east from a band of pro-Russian separatists. 

Just over a month ago, Russia annexed Crimea, the peninsula region in the south of Ukraine with an overwhelmingly large Russian ethnic population. For all the bluster between Washington and Moscow, you’d have thought that Crimea was as important to the international world order in 2014 as Cuba was in 1963 or Hungary was in 1956.

But the world largely seemed to accept Russia’s annexation of a region that was, after all, part of Russia until 1954. Yesterday in Geneva, after as the United States, Russia, Ukraine and the European Union reached a somewhat thin agreement to reduce the current tension in eastern Ukraine, US secretary of state John Kerry tersely declared, ‘we didn’t come here to talk about Crimea.’

So what’s so different now? Will the latest framework, agreed just on Thursday, succeed? Was Crimea just a warmup act for a larger Russian annexation?

What is the Donbass?

The Donbass — or the Donbas (It’s Донбас in Ukrainian, Донбасс in Russian, and if we’ve learned anything about linguocultural conflict, it that language matters a lot) gets its name from the Donets Basin, which is the coal-mining, heavy-industry heart of eastern Ukraine. As a formal matter, the Donbass includes just the northern and center of Donetsk oblast (an oblast is Ukraine’s version of a state), the south of Luhansk oblast, and a very small eastern part of Dnipropetrovsk oblast.  Continue reading All you wanted to know about Ukraine’s Donbass region →
