Answer: Theodore Roosevelt's Foreign Policy.
Explanation:
In that position, young President Theodor Roosevelt considered it an ideal time for the United States to establish itself as the world's largest power. After the American-Spanish war, Zrmlja proved that it was dominant in the military sense, and based on that experience, it continued to build that policy. Roosevelt believed that the United States could be a major factor in the Western Hemisphere. Roosevelt began a project to build the Panama Canal in the early 20th century. That was part of the policy of the "Big Stick". In that way, the united states would realize the intention of the world military leader.
The canal's construction had a financial basis in the context of trade and geostrategic significance. The "Big Stick" policy was also reflected when sending the navy to Colombia; Roosevelt tried to settle the new situation in Panama. In this way, Roosevelt helped Panama enter the world union of countries, but at a certain price. Panama was an American protectorate until the beginning of World War II (1939). Thus Roosevelt ensured the smooth construction of the Panama Canal.
