Russia Wants To Be Back in Charge in Eastern Europe
Since the collapse of the Soviet Union in 1991, Russia has been seen as a second-rate world power, says Chris Miller, professor of international history at Tufts University. Now it is ramping up its military presence on the border with Ukraine, a former Soviet state. "Most of the countries of the region don't want to be controlled by Russia. And so that's what brings us to this point of war," Miller says.
