The difference isn't between control or capture. The difference is between it being a thing that is necessary in war and it being the motivation behind that war

The difference isn't between control or capture. The difference is between it being a thing that is necessary in war and it being the motivation behind that war. If you cut off my access to drinking water by blocking the river that runs through both of our countries you could call my dependence on your exported bottled water "interdependence" if we already have a trade relationship, but if I declare war on you over that it's not "because of interdependence" but "because you were trying to take advantage of me". Interdependence might actually make me less likely to declare war because I have to contrast how much you "stealing my water" hurts me with how much being able to trade with you benefits me and how waging war will affect those things.
