The American continents ... are henceforth not to be considered as subjects for future colonization by any European powers.... We should consider any attempt [by European countries] to extend their system to any portion of this hemisphere as dangerous to our peace and safety. With the existing colonies or dependencies of any European Power we have not interfered, and shall not interfere. But with the governments who have declared their independence, and maintained it ... we could not view any interposition for the purpose of oppressing them, or controlling, in any other manner, their destiny, by any European Power, in any other light than as the manifestations of an unfriendly disposition towards the United States. [The "Monroe Doctrine."]
