Bakker Schut was the president of the National service for the National Plan, secretary of the Dutch Committee for Territorial Expansion, and a member of the State Commission for the Study of the Annexation Question and of the Study Group Territorial Expansion. In his expansion plan, he suggested to annex a large part of northwestern Germany. All the land west of the line Wilhelmshaven-Osnabrück-Hamm-Wesel would be added to the Netherlands, as well as the land east of Limburg, where the border followed the Rhine until close to Cologne, then diverging towards Aachen in the west.
