Some relevant excerpts from the book "Stasi State or Socialist Paradise? The German Democratic Republic and What Became of It" by John Green and Bruni De La Motte
West Germany vs The GDR:
Within weeks of the end of the war, the Soviet occupation forces encouraged the re-establishment of trade unions, cultural organisations and political parties. Already by July 1945, a Kulturbund (Cultural League for the Democratic renewal of Germany) was set up in the Soviet sector to assist with the re-opening of theatres, music venues and cinemas and to promote Germany's democratic cultural legacy as an antidote to Hitler's fascist de-culturalisation and xenophobia.
It took another three months before the formation of political parties and trade unions were permitted in the US sector, which also hindered the setting up of cultural organisations, fearing that they would rapidly become dominated by communists and leftist forces.
In the Soviet zone, which later became the GDR, there was a determined effort to eliminate Nazi ideology and to remove those who were either war criminals or top Nazi activists from all positions of power as stipulated in the Potsdam Agreement reached between the Allies in 1945.
Many of the guilty who had been implicated or had taken an active part in committing atrocities inflicted on Russia and Eastern Europe by the Nazis fled to the West before they could be brought to justice. There they were able to enjoy a comfortable and undisturbed life.
Adenauer‘s own words on being against German Reunification:
Even after it came about, the Soviet Union saw the creation of the GDR as a temporary measure with eventual reunification still the logical outcome. It actually put forward proposals for unification in 1952 but received a hefty 'no' for an answer from the West German Chancellor Konrad Adenauer.
He was an adamant opponent of unification under any circumstances other than under a capitalist system. He famously said that he would “rather have half of Germany completely than a whole Germany only halfway”
Adenauer said in 1954: “The best way to regain the German East is rearmament”. And secretly West Germany was re-armed with the help of the USA.
