"Big Stick" Diplomacy refers to Teddy Roosevelt, the American president most commonly associated with aggressive shows of strength. Roosevelt argued that a good leader should speak softly, and carry a big stick. The big stick referring to the coercive strength needed to backup threats and diplomatic appearances.

The Roosevelt Corollary was made in the interest of intervention. While the original Monroe Doctrine was made solely to warn European nations away from the Western Hemisphere, the Roosevelt Corollary was made to name the United States as the policemen of the Americas.

The Drago Doctrine was announced by Argentina in response to European nations' aggressive debt-collecting actions during the 1902 Venezuela Debt Crisis. It declared that European nations were not allowed to coerce Latin American nations into paying their debts. Roosevelt rejected this Doctrine, and added the Roosevelt Corollary instead, allowing American intervention in countries that couldn't properly conduct their own affairs.

Gunboat diplomacy is most commonly associated with Theodore Roosevelt's aggressive foreign policy. Today, gunboat diplomacy is often used via naval and air deployments to troublesome areas (such as the Strait of Hormuz) to showcase the strength of the American military.

Dollar Diplomacy concerns promising loans and other lucrative economic opportunities to countries to improve diplomatic relations, most commonly associated with William Howard Taft's presidency. Taft's Dollar Diplomacy used incentives, rather than punishments to achieve its goals.

The Carrot and Stick approach involves offering a carrot (positive incentive for good behavior/improved relations), and striking with a stick (negative punishment for bad behavior). The US often used this method in Southeast Asia and the Philippines.

Woodrow Wilson is associated with "moral diplomacy," due to his passionate pursuit of humanitarian policies abroad. Woodrow Wilson accomplished much in his pursuit of a greater global good, winning over countries in agreements many foreign policy experts thought impossible.

The Monroe Doctrine was coined by President James Monroe in 1823 in an attempt to warn European nations against aggressive actions in the Western Hemisphere. The goal was to strengthen the foreign policy of the United States and to become a real world power.

The Monroe Doctrine was introduced by James Monroe in 1823, the fifth president of the United States. Theodore Roosevelt expanded upon the doctrine during his presidency, but did not introduce the original doctrine. James Munroe is also notable because he was the last Founding Father to be President.

While the Monroe Doctrine is named after James Monroe, this was simply because James Monroe was president at the time. The author of the doctrine was the Secretary of State at the time, John Quincy Adams. Monroe was the Secretary of State before Adams.
