The Morgenthau Plan (German: Morgenthau-Plan), first proposed by United States Secretary of the Treasury Henry Morgenthau, Jr. in a memorandum entitled Suggested Post-Surrender Program for Germany, advocated that the Allied occupation of Germany following World War II include measures to eliminate Germany's ability to wage war by eliminating its armament industry, and the removal or destruction of other key industries basic to military strength. This included the removal or destruction of all industrial plants and equipment in the Ruhr.
In occupied Germany, the thinking behind the Morgenthau plan was at first reflected in the U.S. occupation directive JCS 1067 and in the Allied Industrial plans for Germany aimed at "industrial disarmament". Compared with the Morgenthau Plan, however, JCS 1067 contained a number of deliberate "loopholes", limiting any action to short-term military measures and preventing large-scale destruction of mines and industrial plants, giving wide-ranging discretion to the military governor and Morgenthau's opponents at the War Department. JCS 1067 was later replaced by JCS 1779, which aimed at restoring a "stable and productive Germany" and was soon followed by the Marshall Plan.
