Kind of like walling them off and starving them?
http://www.ukrainianmuseum....enocidebyfamine.html"The horrific event, known in Ukrainian as the Holodomor (literally, murder by starvation), took place in 1932-1933, less than twenty years after Ukraine was forcibly incorporated into the Soviet Union. Determined to force all Ukrainian farmers onto collective farms, to crush the burgeoning national revival, and to forestall any calls for Ukraine's independence, the brutal Communist regime of Soviet dictator Joseph Stalin embarked on a campaign to starve the Ukrainian people into submission.
The Soviet government confiscated all the grain produced by Ukrainian farmers, withheld other foodstuffs, executed anyone trying to obtain food, and punished those who attempted to flee. As a result, in the land called the Breadbasket of Europe, millions of men, women, and children were starved to death."
