There were Communists--actual Soviet agents--in the State Department. And the truth is that Truman, and certainly FDR, simply did not view that possibility with alarm.As fantastic as it would seem, based on what we know of Stalinist brutality, many Americans looked positively to the Soviet Union in the FDR era. If liberalism can be described as treason now, the apellation would have been doubly apt then.
Yet we know that the History Channel--which sometimes seems to be the Hitler Channel--can barely find any documenatary footage about the gulag; it's simply flushed down the memory hole. It would take an Oliver Stone of the right to tell the truth about Stalin and FDR's war to make the world safe for Stalin.
We simply haven't got the infrastructure on the right to do the movies that history cries out for. All we have is Rush Limbaugh--and maybe we should take a cue from that.
It would be hard/expensive to produce a video of the McCarthy hearings which fleshed out the whole story but doing a series of radio dramatizations would be far easier/cheaper. That is only one step up from the zero-cost text-based fare we take for granted here on FR. One could also envision a small step up from that, illustrating the spoken text just like Shelby Foote did in his series on the Civil War--but the basic idea is to use the imagination of the listener for the visuals, in conventional radio drama style. Done professionally, it could be a book-on-tape; otherwise it could be done by FR (possibly over phone lines, avoiding the need to assemble the cast at one location) and hosted in the way RadioFR is archived.
If nothing else, the FDR era certainly would be a tempting subject for the next Ann Coulter classic. The defense of McCarthy cannot be merely reactive. Normally "The best defense is a good offense." And when the other guy has no legitimate defense at all . . .
But a strong case could be made that the best way of adressing that era would be fiction. A dramatization of the life of Whittaker Chambers would treat the attractions of Communism--to which Chambers initially succumbed--with respect, and could therefore represent a way of engaging the people who now so readily accede to similar treason.
