First Crimea, then eastern Ukraine? That's what many Ukrainians in the country's eastern region fear, one month after protestors toppled the pro-Kremlin government in Kiev and just days after Russia annexed Ukraine's Crimea in a swift land grab. Now, the rural eastern edge of Ukraine is the site of a Cold War-style stand-off: U.S. military officials tell NBC News that close to 20,000 Russian troops have amassed along the border, backed by heavy armor, and on the Ukrainian side, people have dug a trench through the ground in an effort to stop them from possibly advancing. Elsewhere, north of the city of Donetsk, a pro-Russia militia recently surrounded the gates of a Ukrainian military storage facility to bar trucks from delivering arms to Kiev.
