Which country was particularly upset with the U.S. for getting too close to Venezuela?

The correct answer is Great Britain, as its interests in the region were significantly threatened by the United States' increased involvement with Venezuela during the late 19th and early 20th centuries. The context for this tension stems from the Venezuelan Crisis of 1895, when the United States, under the Monroe Doctrine, asserted its rights to intervene in the affairs of Latin American countries. This put the U.S. at odds with European powers, particularly Great Britain, which had economic and territorial interests in Venezuela and the surrounding areas.

The U.S. stance towards Venezuela exemplified its imperial ambitions and desire to assert dominance in the Western Hemisphere, which Great Britain perceived as a challenge to its longstanding influence in the region. The resulting diplomatic strains led to instances of international tension, including disputes over borders and trade, highlighted by the famous boundary dispute between Venezuela and British Guiana. Ultimately, this situation exemplified the growing unease among European nations regarding U.S. expansionism and its implications for international relations in the Americas.
