Low Countries Ruhr Achilles heel France
Germany justified its invasion of the Low Countries of Belgium, Luxembourg, and the Netherlands in May 1940 by claiming that it suspected that Britain and France were preparing to use the Low Countries to launch an invasion of the industrial Ruhr region of Germany. When war between Germany versus Britain and France appeared likely in May 1939, Hitler declared that the Netherlands and Belgium would need to be occupied, saying: "Dutch and Belgian air bases must be occupied ... Declarations of neutrality must be ignored". In a conference with Germany's military leaders on 23 November 1939, Hitler declared to the military leaders that "We have an Achilles heel, the Ruhr", and said that "If England and France push through Belgium and Holland into the Ruhr, we shall be in the greatest danger", and thus claimed that Belgium and the Netherlands had to be occupied by Germany to protect Germany from a British-French offensive against the Ruhr, irrespective of their claims to neutrality.
