The heartland theory hypothesized the possibility of a huge empire being created which didn't need to use coastal or transoceanic transport to supply its military–industrial complex, and that this empire could not be defeated by the rest of the world allied against it.
Teorija Heartlanda, u drugu ruku, pretpostavlja mogućnost nastanka ogromnog carstva koje ne bi trebalo koristiti obalni ili prekooceanski prijevoz radi opskrbe svojega vojnog industrijskog kompleksa, te takvo carstvo ne bi ni čitav ostatak svijeta udružen protiv njega mogao poraziti.
