Explanation:
The "Big Stick" foreign policy was the common name given to the addition of the Roosevelt Corollary to the Monroe Doctrine, after President Roosevelt's quote "speak softly, and carry a big stick, and you will go far".
The Big Stick, or Roosevelt Corollary stated that the United States might intervene in American affairs to prevent European attacks on American countries. He stated that the United States would act as a mediator between American countries that were in debt with European countries, and that if they failed to pay ,U.S. military forces would step in.
