Politics. There are obvious strategies (bomb everything, if war still not over, build bigger bombs and GOTO 10), but that sort of demotivates humans and they stop the war.<p>It&#x27;ll be interesting (as in the old fake Chinese curse interesting) to know what happens when less democratic power structures wage war. They are still constrained by economics (trade creates value, if they bomb the shit out of someone they might find themselves cut off from trade, see embargoes and sanctions on Russia) and the possibility of an internal struggle (civil war) is always there.
