Well, the 1948 story when he GDR was founded, based on Soviet occupation zone is well known. The story repeated later in Korea, and you know the result...
Again, as usual, you accuse evil Russians of something they never did. Berlin was divided into occupation zones (extremely stupid from my POW - why let the "allies" control what we fought for?), and it was the "allies" problem how to supply their anclave.
IMHO, the very existance of West Berlin was a quiestion of good will from Soviet side.
The Berlin highway was an unbelievable thing. My Grand Dad was a moblie missile-technical base commander in E. Germany in late 50s - early 60s. Several times he had to arrest american "tourists" who drove in the middle of a convoy that carried nuke warheads.
Civil war in Russia involved US occupation forces in Archangelsk and Far East, and resulted in uncovered stealing of Russian weapon and gold stocks. We still pay for weapons stolen by US "expedition corps". I bet you never read about it in your history books.
Huh... If only Allied nations decided to crush bolsheviks in 1918, but they preferred to simply plunder what possible in Russia
