I told the Secretary that the declaration of the President and the known friendly disposition of the Government and of the people of the United States towards these countries did not confer upon this Government the privilege of demanding our interference as a right.
OBSERVATION: Poinsett explains that despite the amicable relations between the US and the Latin American nations, there was no obligation on the part of the US to interfere in Latin American skirmishes such as the attempted invasion of Cuba by France.
INTERPRETATION: Poinsett is relaying clarifications on the part of the administration at the time, who were not keen on having demands made by other countries whom they had no intention of involving themselves officially with.
CONNECTION: The tertiary source notes that although the Monroe Doctrine made a strong declaration that invasion of any of the Americas by European nations will not be tolerated by the US, the people behind it (particularly Henry Clay) quickly changed their stance on US interference with other nations' affairs, choosing to take a more neutral stance and deny any obligation to help anybody beyond their borders.
CHANGE OVER TIME: The US went from boldly positioning themselves as a guiding figure for other nations and a powerful force against European invasion to recoiling and attempting to distance themselves from foreign affairs.
