the war was just getting started between the USA and the USSR the 2 superpowers
Stalin wanted to destroy Germany – Britain and the USA wanted to rebuild Germany.
The Russians were taking German machinery back to the USSR. In January 1947, Britain and the USA joined their two zones together to try to get German industry going. They called the new zone Bi-zonia (‘two zones’).
Congress voted for Marshall Aid on 31 March 1948. Immediately, the Russians started searching all road and rail traffic into Berlin.
On 1st june they intorduced a new currency into Bizonia, the next day the Russians stopped all road traffic into Berlin. It had been the final straw.
The western powers said Stalin was trying to force them out of Berlin.
