{The United States is virtually an island nation bordered by two oceans and the thinly peopled Canadian Arctic to the north. Only to its south is it threatened by the forces of Mexican demography.}
The United States is largely insulated from the rest of the world due to its geographic position, surrounded by two vast oceans and a sparsely populated area to the north with Canada. This unique location has shaped its political and social dynamics, allowing it to develop largely in isolation compared to other nations.
However, the nation faces demographic pressures from Mexico to the south, highlighting a critical vulnerability. This dynamic suggests that while the U.S. enjoys significant geographic advantages, it must remain conscious of the threats that arise from changing demographics in neighboring regions, as discussed by Robert D. Kaplan in "The Revenge of Geography."
