Ack, no I didn't know that about Quisling. Well our own most famous traitor, Benedict Arnold, was the most able general we had at the start of the American War of Independance. He won our first victory at the battle of Saratoga, without which we never would have garnered support from France and been able to defeat the British. He was rather arrogant of his abilities however and that's what led to his switching sides to the British. Once he did their bidding he was ignored by them. Interesting that both Quisling and Benedict Arnold have had their very names become synonyms for "traitor". You can't be more scurilous than that.
