Who was the President known for the phrase "speak softly and carry a big stick" during the era of Imperialism?

The phrase "speak softly and carry a big stick" is famously attributed to Theodore Roosevelt, who served as President from 1901 to 1909 during a time of significant American imperialism. This phrase encapsulated Roosevelt's approach to foreign policy, emphasizing diplomacy backed by the threat of military power. Roosevelt believed in negotiating peacefully while having a strong military ready to enforce American interests if necessary. This philosophy guided his actions in various international situations, such as the construction of the Panama Canal and the enforcement of the Monroe Doctrine in Latin America.

The other presidents listed had different policies and approaches during their respective terms, but none are directly associated with the phrase or its implications as intimately as Roosevelt.
