Why was the control of North Africa vital for the both the allies and axis​

The Allied victory in North Africa destroyed or neutralized nearly 900,000 German and Italian troops, opened a second front against the Axis, permitted the invasion of Sicily and the Italian mainland in the summer of 1943, and removed the Axis threat to the oilfields of the Middle East and to British supply lines to Asia and Africa. It was critically important to the course of World War II.
