Mr. Savlov, Somehow, you and Morris managed to half-heartedly compare the Vietnam War to the Bush administration ["Being Robert McNamara," Screens, Feb. 20]. I am amazed that both of you are privy to what is actually going on behind the scenes at the Pentagon and White House. If it has taken this long for a lot of the information on the Vietnam War to surface (tapes, documents, etc.), how are you two able to draw comparisons without knowing the outcome of our current war? It sounds as irrational as the Hitler-Bush comparisons. It seems strange that conservatives long for the righteousness of World War II while the liberals are somewhat nostalgic for the social protests centered on the Vietnam War. One might be led to believe that both groups have developed a fetish for war.
