Though they tried to escape blame for decades, the Soviet responsibility for the Katyn Massacre has been known for some time. Now it appears that our government helped cover it up. Of course, most wars are accompanied by propaganda on all sides. But some is worse than others.
This story reminds me of Evelyn Waugh's Sword of Honor trilogy, when the protagonist-- who initially enlisted thinking the war was for a noble cause-- realized that his country's pact with communism led to an horrific outcome for those countries put under Soviet domination and moreover put socialists in control in England.
Pat Buchanan called World War II "the unnecessary war". It was, though it is considered an unquestionably noble cause for nearly everyone who studied in in American schools. Yet, as Buchanan notes, it's not easy to see what this country gained in siding with one totalitarian regime over another, half a world away.
World War II defines our country, much as the Civil War did for those who came before it. It would be nice to appraise the mythos based on reality.
