Interesting, looking at history, I'm not sure if "That’s why we fight wars" is valid at all - perhaps in some exceptions, but almost always not. The dominant reason for fighting wars has always been accumulating power and wealth, enforcing control and removing threats, all kinds of practical political reasons. Often some ideas or ideologies were used to motivate people to support a war or to participate in it, but as a rule they were just a small part a reason for the war itself. For example, various religious conflicts in Europe almost always have very practical reasons for being started, and religious ideas being raised as an artificial justification and motivation; WW2 was not really fought over ideologies (even though it was often framed that way in propaganda), the allies would happily tolerate fascism and holocaust if Hitler had kept to his borders; and in modern times its obvious that people aren't willing to fight wars over ideas but are willing to do so for either minerals or internal fighting to see which "clan" will get to be in power.
