Final answer:
General Ira Eaker was the figure who convinced Winston Churchill to allow US precision bombing of German targets during the day to complement British night bombings.
Explanation:
The Oklahoma general who convinced UK Prime Minister Winston Churchill to allow US air forces to bomb German military targets with greater precision during daytime hours was Ira Eaker. The strategy behind this decision was that the United States would precision bomb industrial and military targets during the day, complemented by British bombers that would area bomb cities by night. This approach was part of the Allies' strategic bombing campaign to disrupt Germany's ability to make war by targeting factories and transportation lines. It also exploited the strengths of American bombers and targeted capabilities, which excelled at precision bombing due to their advanced Norden bombsights.
