US Presidency
1847

To act otherwise in the existing state of things in Mexico, and to withdraw our Army without a peace, would not only leave all the wrongs of which we complain unredressed, but would be the signal for new and fierce civil dissensions and new revolutions all alike hostile to peaceful relations with the United States. Besides, there is danger, if our troops were withdrawn before a peace was conducted, that the Mexican people, wearied with successive revolutions and deprived of protection for their persons and property, might at length be inclined to yield to foreign influences and to cast themselves into the arms of some European monarch for protection from the anarchy and suffering which would ensue. This, for our own safety and in pursuance of our established policy, we should be compelled to resist. We could never consent that Mexico should be thus converted into a monarchy governed by a foreign prince. Mexico is our near neighbor, and her boundaries are coterminous with our own through the whole extent across the North American continent, from ocean to ocean.
