This sounds like a reasonably good book on the immediate aftermath of the War, (a period as fascinating as the war itself, from a geopolitical viewpoint). I would disagree with the author's and reviewer's sentiment that this story has never been told. Perhaps not as well as they think it should be, or in one book, (I don't know, I have yet to read it for myself); but the post war situation is well written about, at least from a scholarly point of view - if you're willing to look for it, rather than wait for it to be spoon fed to you from the mass media, (like the Post). There are excellent articles and books on Russia's activities in the conquered lands, the Greek civil war, the occupation of Germany and the treatment of its POW's, post war positioning of Italian partisans, the Finnish predicament, the Yugoslav cauldron, etc. You've just got to look for them. I'm unaware of anything offhand about the Lowlands or occupied Scandinavia in the late 40's, but that's because I've never tried to find anything.
There is an area of study that I am unaware of any serious reporting on. There were rumors within certain circles of a possible coup in West Germany in the mid to late 50's. It was to be both anti-American and Russian. I can't find out if it's true, or not.
