In that case, sorry I guess? Since I myself pointed out that that’s how it worked over 100 years ago I thought it was pretty obvious I was aware it didn’t work that way anymore, so I interpreted your comment as refuting my primary point (the one stated explicitly above). If that’s not what you meant to do then I don’t think we really have any disagreement.
I honestly don’t see what you mean? It’s true that people in power have waged war on each other more or less throughout all of known history, no?
Whether or not said people had to actually take part in hostilities doesn’t seem to have much impact on whether they choose to wage war. Or do you have a counter example (a society that has changed whether it waged a bunch of wars based on whether its leaders had to fight in them)?
