“The most famous of them was Adolf Heusinger, chief of the Operationsabteilung from 1940-1944. He was actually Hitler’s chief of staff and helped plan the Nazi’s invasions of Poland, Norway, Denmark, and France. He was promoted to colonel on August 1, 1940 and became chief of the Operationsabteilung in October 1940, making him number three in the Army planning hierarchy.
After the war, this German war criminal, the man who helped Hitler plan and execute his invasion of neighboring countries which directly led to the deaths of millions of people, was not even put on trial, quite contrary he was allowed to take over the newly established West German army, the “Bundeswehr”.
In 1961, Heusinger was made the Chairman of the NATO Military Committee (essentially he was NATO’s chief of staff). He served in that capacity until 1964.”
