As soon as Churchill learned of the atomic bomb's existence, he wanted to use it against the Soviet Union! Professor Gabriel Kolko
Not a direct quote, just an innuendo.
Can you give me some larger quotes? I looked on the net too, and this was the only site that had these quotes. It seems that the Field Marshall and Churchill didn't have a good relationship, and I have read that Chuchill had an infantile streak, so I could imagine him saying possibly something like this in private.At Potsdam, Churchill `urged that they consider it as a diplomatic lever on the Russians'.
