By the time World War II ended, most American officials agreed that the best defense against the Soviet threat was a strategy called “containment.” In his famous “Long Telegram,” the diplomat George Kennan (1904-2005) explained the policy: The Soviet Union, he wrote, was “a political force committed fanatically to the belief that with the U.S. there can be no permanent modus vivendi [agreement between parties that disagree].” As a result, America’s only choice was the “long-term, patient but firm and vigilant containment of Russian expansive tendencies.” “It must be the policy of the United States,” he declared before Congress in 1947, “to support free peoples who are resisting attempted subjugation…by outside pressures.” This way of thinking would shape American foreign policy for the next four decades.
5. The United States wanted to acquire the Mexican Cession to B. complete the transcontinental railroad across the Southern United States.
However, it is important to note that this is also part of the Manifest Destiny. However, in this case, the more accurate answer is B, as the Gadsden purchase was used to create a easier route for the railroads to get laid (as the area surrounding were mountainous). However, it also played an important role in the Manifest Destiny, as it continued the policy of continuing to expand westward (though south west).
6. I believe it is A. Factors of the Creation of the Monroe Doctrine., especially in the long run.
The Monroe Doctrine was created during the presidency of James Monroe, who was office from 1817 - 1825. You must remember that the Louisiana Territory was under French rule, Florida, and south-western parts of the United States was under Spanish rule, and other European countries claiming smaller territories within the current US. However, with the purchase of the Louisiana Purchase as well as the Gadsden Purchase and the Acquisition from both the Texas Independence (in which Texas joins the Union), and the Mexican-American War, the US gained large amounts of territory at once, as well as large amounts of population. The Monroe Doctrine was an ultimatum to European countries, in which the US was the regional power, and that it would use it's resources to "protect" it's neighbors and it's own interests. In this case, the European countries were not to interfere with territories in the US, creating the U.S. sphere of influence. However, existing colonial powers were not removed by the U.S.
