Final answer:
Roosevelt's big stick foreign policy involved using the threat of military force to negotiate trade agreements, while Taft's dollar diplomacy focused on using economic power. The big stick policy was more successful in maintaining American power.
Step-by-step explanation:
Roosevelt's "big stick" policy and Taft's "dollar diplomacy" were two different approaches to foreign policy.
Roosevelt's policy involved using the threat of military force to negotiate beneficial trade agreements and maintain the United States' status as a world power. He believed that the use of force was unnecessary as long as the military had the ability to threaten force.
Taft, on the other hand, focused on using U.S. economic power to influence foreign affairs. He aimed to secure markets and opportunities for American businessmen by using the threat of American economic clout.
While both approaches had their successes and failures, it can be argued that Roosevelt's "big stick" policy was more successful in terms of maintaining American power and influence.
