The Cold War was a state of geopolitical tension between the Soviet Union with its satellite states (the Eastern Bloc), and the United States with its allies (the Western Bloc) after World War II.
The Cold War refers to global tensions between the United States (USA) and its allies and the Union of Soviet Socialist Republics (USSR) and its allies. Some of the deeper issues that set the USA and the USSR at odds were that the USA was committed to capitalism and democratic institutions of government, whereas the USSR was committed to communism and imposed authoritarian government. The Cold War was mostly a tension between these worldviews.There were also immediate conflicts and pressure points as the Cold War began. One of those issues was that the USA had atomic weapons and the USSR did not. (The US would not share that technology with the Soviets, who had been their ally in World War II.) When the Soviets developed their own atomic weaponry, this led to a massive arms race between the superpowers, which also was a big feature of the Cold War.
United States and France came into the agreement of the land which is popularly termed as The Louisiana Purchase. It was the United States that acquired the large part of the land situated in the west of the Mississippi River. The territory of Louisiana covered the area as Mississippi river in the east to the Rocky mountains in the west. It stretched from the Gulf of Mexico in the south the Canadian border in the north.
