AP Success - AP US History: The Monroe Doctrine

Our policy, in regard to Europe, which was adopted at an early stage of the wars which have so long agitated that quarter of the globe, nevertheless remains the same, which is, not to interfere in the internal concerns of any of its powers; to consider the government de facto as the legitimate government for us; to cultivate friendly relations with it, and to preserve those relations by a frank, firm, and manly policy, meeting, in all instances, the just claims of every power; submitting to injuries from none. But, in regard to those continents, circumstances are eminently and conspicuously different.
It is impossible that the allied powers should extend their political system to any portion of either continent, without endangering our peace and happiness; nor can any one believe that our Southern Brethren, if left to themselves, would adopt it of their own accord. It is equally impossible, therefore, that we should behold such interposition, in any form, with indifference. If we look to the comparative strength and resources of Spain and those new governments, and their distance from each other, it must be obvious that she can never subdue them. It is still the true policy of the United States, to leave the parties to themselves, in the hope that other powers will pursue the same course.
