A few more comments: the CIA's "Chernobyl Accident" video is probably the least-interesting of the group, except as a historic snapshot of the guesswork that US analysts were attempting to do immediately after the disaster. But from today's standpoint, there are no surprising revelations, and you can get a far more detailed analysis of Chernobyl from Wikipedia, thanks to two decades of candor in the post-Soviet period.

"The Andropov Succession" is marginally more interesting in that it shows CIA analysts attempting to predict something that hadn't happened yet (namely, who would be picked to replace Andropov), rather than discussing something that had already occurred, as with the Chernobyl disaster. But again, kinda boring for a viewer today.

The "Soviet Space Program" short also contains very few or no surprises. However, it's notable for the mixed attempt to give the "enemy" its proper credit for technical innovations, while at the same time demonizing the USSR in a rather unsubtle way, by repeatedly referring to the "Jekyll and Hyde" character of the Soviet space efforts. (I.e., the scientific missions were Jekyll, while the military missions were Hyde). Needless to say, the US space program itself has always had a "Джекил и Хайд" character, if you want to insist that scientific applications are Jekyll and military applications are Hyde!
