canard in the coalmine

"The claim that Roosevelt betrayed Eastern Europe at Yalta, and that he set the stage for 40 years of Soviet domination, is an old right-wing canard. By repeating it, and by publicly charging that the Yalta agreement was in the "unjust tradition" of Hitler's deal with Stalin, Bush was simply engaging in cheap historical revisionism. His glib comments belong to the Ann Coulter school of history." LINK
