Good Stuff Anni .
Can only add . that in addition to warnings from his own spy network Stalin, prior to Operation Barbarossa (the german attack on russia) was repeatedly warned by the British of Germanys intentions but apparently chose to ignore those warnings . Many military analysts ascribe the astonshing early German success in the campaign to the fact that the officer class of the Red Army had been decimated in earlier years by Stalins paranoia . Thousands executed and thousands more sent to the gulags . Many were eventually repatriated back to the army when Stalins fear over defeat grew bigger than his paranoia .
