Answer:
The answer is "The debate over where the Allies should attack first."
Step-by-step explanation:
At the Casablanca Summit, January 14-24, 1943, Winston Churchill and F.D. Roosevelt agreed on concentrating the main allied effort on Europe and Germany, and on increasing supplies to the Soviet Union. They decided to focus on the Mediterrenean Sea in order to prepare for an invasion of Italy to get that German ally out of war.
