USSR: in October,1946 Uncle Joe was not yet seen in the colours he later displayed
Disagree. Stalin never changed that much - even before 1945 the USSR was spectacularly unco-operative (shuttle bombing? Tirpitz attacks?) while of course sucking up all help/resources we offered. As Churchill demonstrated in his speech of March 1946, he was already well aware of the emerging threat. Giving the Nenes to the USSR was appallingly naive.
