If memory serves, when the Soviets assumed power in Russia, the Ukraine was forced to turn over its crops to Russia which produced a famine in the Ukraine which claimed the lives of 10's of millions. When the Nazis invaded, that many in the Ukraine  sided with the Nazis,  should come as no surprise.  If an argument is made that anti-semitism was a fact in the Ukraine before the famine, I would not disagree-however anti-semitism was rife throughout eastern Europe then and remains a factor today.  So, if Ms. Freeland's grandfather worked for a Nazi newspaper,  it may have been understandable when the alternative was to work for the Soviets. 

All that aside, Ms. Freeland owes no one an apology for the actions of her grandfather.  Additionally, one might equally argue that her family history may make her more, rather than less, qualified to understand what type of regime Mr. Putin is attempting to re-create from the ashes of the USSR.
