Goebbels pressured Hitler to introduce measures that would produce "total war", including closing businesses not essential to the war effort, conscripting women into the labor force, and enlisting men in previously exempt occupations into the Wehrmacht.
Guadalcanal soon became a focal point for both sides with heavy commitments of troops and ships in the battle for Guadalcanal. By the start of 1943, the Japanese were defeated on the island (Guadalcanal) and withdrew their troops. Operation Ke was a largely successful withdrawal of Japanese forces from Guadalcanal. The operation took place between 14 January and 7 February 1943. The withdrawal was carried out on the nights of 1, 4, and 7 February by destroyers. And on 9 February, Allied forces realized that the Japanese were gone and declared Guadalcanal secure, ending the six-month campaign for control of the island.
At the Casablanca Conference in early 1943, the Allies reiterated the statements issued in the 1942 Declaration, and demanded the unconditional surrender of their enemies. The British and Americans agreed to continue to press the initiative in the Mediterranean by invading Sicily to fully secure the Mediterranean supply routes.
In January 1943, Churchill met Roosevelt at the Casablanca Conference (codename Symbol), which lasted ten days. It was also attended by General Charles de Gaulle on behalf of the Free French Forces. Stalin had hoped to attend but declined because of the situation at Stalingrad. Although Churchill expressed doubts on the matter, the so-called Casablanca Declaration committed the Allies to secure "unconditional surrender" by the Axis powers.
On 15 January 1943, Hitler appointed Goebbels as head of the newly created Air Raid Damage committee, which meant Goebbels was nominally in charge of nationwide civil air defenses and shelters as well as the assessment and repair of damaged buildings.
After receiving an enthusiastic response to his speech of 30 January 1943 on the topic, Goebbels believed he had the support of the German people in his call for total war.
