Answer: The actions of president Theodore Roosevelt helped move the united states into a position of world power since the entry of usa to the second world war.
Step-by-step explanation:
The United States entered World War II, on December 8, 1941, following the attack of the Japanese Empire on the North American Pacific fleet based on Pearl Harbor. The government obtained a modification to the Neutrality Law that allowed it to sell arms to the Allies.
As for Europe, the United States through 1942 limited itself to ensuring that Britain was not invaded, maintained the flow of armaments for both the British and the Soviets, and dedicated itself to gaining control of the Atlantic sea routes. Using Britain as an air base, the US Air Force began a strong offensive on Germany's industrial, transportation and population centers.
In the Pacific, and after a series of major defeats, the United States turned a large part of its war effort by developing a strategy aimed at controlling the entire Pacific basin, which is why the US high command focused on the development of naval aviation and in assault troops. The United States supplied the Chinese nationalist armies fighting the Japanese, and supported partisan groups in the Philippines and Southeast Asia.
The war transformed the United States. It was the war that brought the United States out of the Great Depression, which transformed its social structure by incorporating millions of women and blacks into industrial work, which created the basis of what Eisenhower called the industrial military complex and which converted to this country in a world power. The war also had effects on its citizens. Millions of Americans saw the world for the first time. In the war, the United States not only developed its economic, military and nuclear power, but also accumulated a symbolic and strategic power from proclaiming itself as a defender of democracy and freedom.
