There's not more territory in any meaningful sense though, and without territory there are no resources. Consider the WW2 era German interest in lebensraum, the Japanese interest in the northern resource region of Siberia ( https://en.wikipedia.org/wiki/Kantokuen https://en.wikipedia.org/wiki/Kantokuen ). Since WW2, in theory borders are supposed to be basically frozen and war is technically illegal, but clearly Russia would like to annex something extra. More subtly there are all the soft-power machinations or straight up proxy wars that are energy/resource related, and typically wherever one great power has influence they'll try to freeze out others. Looking forward further, there's only one moon, one solar system..
