The Army was the only organisation in Germany with the capacity to overthrow the government; from within it, a small number of officers came to present the most serious threat posed to the Nazi regime.[4] The Foreign Office and the Abwehr (Military Intelligence) of the Oberkommando der Wehrmacht (Supreme Command of the Armed Forces) also provided vital support to the movement.[5] Hitler's 1938 purge of the military was accompanied by increased militancy in the Nazification of Germany, a sharp intensification of the persecution of Jews and daring foreign policy exploits.
