I think this is skewed by your perception of how frequent wars actually are. If your idea of a typical war is Trump bombing Iran, well, I disagree with your assertion, but it's at least a colorable argument. But those kinds of wars between clearly defined states are actually incredibly rare.

Your typical war, however, looks more like the M23 rebels (backed by Rwanda, though they deny this) fighting the Congo state. Take a more expansive definition of war to include armed conflict in general, and the typical case looks more like the ELN in Colombia. Almost all of these kinds of conflicts can be fairly analyzed as fighting for control of resources, chiefly land and the people or the rents that can be derived from de facto control of that land.
