A poor assumtion. I'm not sure who this letter was aimed at, but I would assume they are leftists. Left-wing ideology is indeed a religion, albeit one with out God and with western civilization and the Unitied States in particular in the role of the Devil. Therefore all forces attacking the the USA are beyond reproach, and all actions taken by us are inherently evil. Some leftists will make an exception for WWII, but only because Hitler was not only undeniably evil, but more importantly the mortal enemy of the Communist USSR. Not even the fall of the Soviet Union and subsequent exposure of Communism for the fraud it was has changed the "religious" catechism of the left.
