US Containment Policy is a foreign policy strategy created and executed by the US after WWII founding it’s first key purpose in the Truman Doctrine of 1947. President Harry Truman warned of the evils of communism<span> that threatened the democratic freedom of its people which like the US, the Soviet Union wanted a world modeled on their own country’s society and values. Even though the Soviet claimed they provided all citizens with economic and social rights, the US saw communism as a slave state that control the private life and thoughts of its citizens. A threat that violated both democratic rights and civil liberties of its citizens and therefore required the continued efforts of America to make sure that it did not spread to the United States and other nations that have not yet moved politically towards Soviet Union communism. As such, this Policy of Containment stated that the US would try to stop (contain) the spread of Communism by creating strategic alliances or support to help weak countries to resist Soviet advances.

Military: Germany was limited to a very small military (no more than 100,000 men of all ranks), and was not allowed to have any heavy artillery. This was to prevent Germany from gaining a military strong enough to launch another attack, but since a strong military was a very important part of remaining a world power, this meant Germany could never hope to achieve this whilst honoring the treaty.
Economic: Germany was forced to pay reparations (as they were being blamed for the war) to many countries, mainly Belgium and France. The amount was far to much for Germany to ever pay off, and was a key factor in Germany's economic crisis shortly thereafter.
Territorial: Germany was forced to give up all of it's colonies, which were given to various League of Nations powers. This was a major loss of land and population for the country, not to mention a loss of money from said colonies, again leading back to economics.
It first started with the Pearl Harbor Attack and was officially announced by Roosevelt in the Quarantine Speech.
