The correct answer is Theodore Roosevelt (United States)

• Nobel Year: 1906
• Position: 26th President of the United States (1901–1909)

The Philippine-American War. Which coincidentally was a war he inherited from his predessor much like Obama inherited the Afghanistan War from Bush.

. Based on US military actions that occurred during Theodore Roosevelt's lifetime, particularly the Philippine-American War, it is estimated that hundreds of thousands of Filipino civilians were killed by Americans through violence, famine, and disease. Roosevelt served as president from 1901 to 1909, during which time the brutal conflict continued.

• Filipino resistance: The Filipino revolutionaries, led by Emilio Aguinaldo, had fought alongside American forces to defeat Spain, believing it would result in their independence. When the U.S. Senate ratified the treaty and annexed the islands, the Filipino nationalists felt betrayed and resisted the new occupation.
• War atrocities: The conflict was brutal on both sides. U.S. forces committed atrocities, including burning villages and employing torture, while Filipino fighters tortured captured soldiers and terrorized civilians who cooperated with American forces. An estimated 200,000 Filipino civilians perished from violence, famine, and disease.
• Shift in U.S. foreign policy: For the U.S., the acquisition of the Philippines signified a dramatic shift from isolationism to imperialism. The war and subsequent occupation sparked a political backlash from anti-imperialists in the U.S. who argued against expansionism.
