"It was on 7 March 1936 that Hitler comprehensively violated the Versailles Treaty by sending troops into the industrial region of the Rhineland, which under Article 180 had been specifically designated a demilitarized zone. Had the German Army been opposed by the French and British forces stationed near by, it had orders to retire back to base and such a reverse would almost certainly have cost Hitler the chancellorship. Yet the Western powers, riven with guilt about having imposed what was described as a ‘Carthaginian peace’ on Germany in 1919, allowed the Germans to enter the Rhineland unopposed."
