Standoff in Ukraine

The allure of the West has helped shape Russian history since Peter the Great three centuries ago. Now it’s shattering even older bonds with Russia's neighbor, Ukraine. In 2013, a rebellion sparked by pro-European Ukrainians seeking a decisive break from the nation’s Soviet past set in motion a chain of events that created the tensest standoff between Russia and the West since the Cold War. Russian President Vladimir Putin annexed Ukraine’s Crimean peninsula in March 2014, proclaiming a duty to defend the ethnic Russians who dominate the population there and sending shockwaves through the post-World War II order.
