"With equal advantages of soil and climate, the inferiority of the Spanish and Creole character tend to place the countries inhabited and administered by them, even under the best possible systems, far, very far behind those in which the Anglo-Saxon element it allowed to operate...The Anglo-Saxons have been sweeping everything before them on the North American continent, and establishing an empire which is felt, respected and feared, in every quarter of the globe...Will the love of enterprise, and the desire of a more extended territory, already so plainly manifested among us, lead to excursions upon the impotent neighbors that surround us upon every hand? Have not results in Mexico taught the invincibility of American arms? What power on this continent is there that can arrest their progress? What army that would not be shattered to pieces in the encounter?...The North Americans will spread out far beyond their present bounds. They will encroach again and again upon their neighbors. New territories will be planted, declare their independence, and be annexed! We have New Mexico and California! We will have Old Mexico and Cuba! Time has all of this in her womb. A hundred states will grow up where now exists but thirty.
- J.D.B. DeBow, a spokesman for the Southern cotton aristocracy, July 1848.
