Isolationism is a doctrine practiced by the United States during a large part of its history with the objective of not intervening in external affairs that did not pose a real threat to their country.

The beginning of the twentieth century brought with it problems that occurred in Europe and the Pacific, and this would end in large part with the isolationist feelings of the United States. The annexation of the Philippine Islands during the Hispano-American War of 1898 displaced US interests to the western Pacific Ocean, at the gates of Japan. USA UU he did not know how to perceive the threats against his position of neutrality. This caused the submarine war of Germany during the First World War, whose objective was to avoid the arrival of supplies towards the British Empire. When the war ended, EE. UU he forgot his new alliances; both the Treaty of Versailles and the League of Nations found little support from Congress.

In 1901 President William McKinley was assassinated and succeeded by Roosevelt, who was then 42 years old and thus became the youngest president in the history of the United States and the first since 1865 who had not fought in the Civil War. Roosevelt tried to turn the Republican Party towards progressivism, including the fight against monopolies and the regulation of companies. He coined the phrase "Square Deal" to describe his internal politics, emphasizing that the ordinary citizen would have his fair share under his policies. As a lover of nature, he promoted environmental conservation. On the international stage, Roosevelt's policies were characterized by the doctrine of the Big Stick. He promoted the completion of the Panama Canal, sent the Great White Fleet to circumnavigate the world to demonstrate the power of his nation and negotiated the end of the Russo-Japanese War, for which he was awarded the Nobel Peace Prize, thus becoming in the first American to win a Nobel prize.
