Federalism limits the power of government in the United States through the creation of two sovereign powers: the national government and state governments. In this way, it regulates the influence these have. Separation of powers establishes internal limits; it divides government against itself, giving separate functions to different branches and compelling them to share power, so neither of them becomes predominant.
By separating powers, these are split among the executive (president, vice president, Cabinet), legislative (Congress, House of Representatives and Senate), and judicial branches (Supreme Court and other courts), which are definite departments of American national government.
The Cold War really began before WW II as the US and Russia had 2 very opposing views of government and didn't trust each other. However, during the war, the two countries had to put their differences aside to beat Nazi Germany. Towards the end of the war, it was evident that heat was building up between the two countries again. The Soviets were taking liberties in areas that suggested they were not only interested in winning the war but taking land also. They insisted they control Berlin at the end of the war, wanted Manchuria for their own and not to give back to China, insisted they be in charge of Postwar Japan operations (MacArthur said absolutely not) and were really upset that the US had the power to use a nuclear bomb that they didn't even know existed. The Soviets were also aggressive after the war in areas such as Korea and Viet Nam with "support".
