I was also part of a post-Vietnam generation that had learned to question its own government and saw how - from the rise of McCarthyism to support for South Africa's apartheid regime - Cold War thinking had often led America to betray its ideals. This awareness didn't stop me from believing we should contain the spread of Marxist totalitarianism. But it made me wary of the notion that good resided only on our side and bad on theirs, or that a people who'd produced Tolstoy and Tchaikovsky were inherently different from us. Instead, the evils of the Soviet system struck me as a variation on a broader human tragedy: The way abstract theories and rigid orthodoxy can curdle into repression. How readily we justify moral compromise and relinquish our freedoms. How power can corrupt and fear can compound and language can be debased. None of that was unique to Soviets or Communisists, I thought; it was true for all of us. The brave struggle of dissidents behind the Iron Curtain felt of a piece with, rather than distinct from, the larger struggle for human dignity taking place elsewhere in the world - including America.
