Sure, but I was thinking of it more generally. Humanity as we have known it, has always been at war. I once heard it said, that being at war is the default state for humanity. Not everyone knows it, but those who understand this (in governments, the military and in other areas of society) tend to "play the game". Acquiring more resources, land and to then be able to decide how people should be and live in those areas. It seems for the most part, to be the present reality still, even if it has become more sophisticated, than in the past. So if that is a given, then the reality is that people will continue to fight, until somebody (a grouping) of people eventually "wins" it all (unless it ends before that, or something else happens). Like the song, "Everybody wants to rule the world" (One headline, why believe it?). Those with more influence and power, will be able to do more of it while they hold the power to be able to do it to the others, who have less influence at that time. But if the tables turn, then the same thing happens again. Governments strive for influence and power, so they will use whatever tools they feel they need to use and have at their disposal.
I've seen (i.e. read their comments) a person (or persons) from the US, who says he/they have a connection with the MIC, literally laughing at Russia. He (or they) project/s the idea that Russia is bluffing and so they will never use their nukes. There are people who literally think that Russia is weak and that it will eventually be collapsed and then broken up into a bunch of smaller countries. I believe, based on them saying such things, that they have no doubt in their mind about what "the game" is all about, as they see it. It's about ruling the world and coming out on top (and think they think they can do it). So, war in their minds is seen as a good and necessary thing since it's inevitable anyway (so, why waste time with stalling) and looking at the world like a chess board. (edited, after I realised an inaccuracy)
But what I wonder about is what China makes of all of it and what will they be doing in the meantime. If they can see "the game" that has been going on (and it's probably a given that they can and they know), then what are they going to do in preparation for if/when it is their turn to be threatened. These same people mentioned earlier, don't seem to think China is a big deal either, because they have some demographic problems. But from what I've understood, the Chinese are a proud Nation, perhaps even more than Russia(?). For a long time I didn't want to think it, but it does seem to be the case, that the reality is that people will continue to fight, until someone eventually wins "the game" and then becomes "the boss" (or close enough to it), at least, or so it appears.
Russia has not invaded the same amount, but, that could just be because they weren't ever strong enough, or felt in a position to be able to do it. (They didn't get to have the Petro dollar, the US won that one.) But there is human nature all around, that is universal.
People can and do adapt to conditions, though. I'm not a history expert by any means, so please don't quote me, but for instance, if one looks at a smaller Nation like Japan and how much they have adapted and changed. They used to invade other countries. they were said to have been quite brutal in war, but then they lost (and were nuked). Now, that is considered history by the new generations and in general, the Japanese people seem to absolutely love the USA and feel close to the USA. Basically, the USA is seen like a big brother. Japan is now full of cute stuff everywhere and that has become a known characteristic of the culture (kawaii), and they feel that Japan and the USA respect each other and each other's culture.
"If you can't beat them, join them". But, people will try to beat the other, first. So, I tend to think that it's mostly just a matter of how far nations think they are going to be able to push others, and then once that has been figured out, it gets acted on accordingly. I could be completely mistaken, but that is at the moment how it seems to me.
