I understand that someone who spearheads peace can be surrounded by propaganda from many sides. Today, that propaganda can take the form of fake news, Pallywood, and the human rights "watching" organizations being bought and owned by the actual enemies of humanity. Because of that situation, I suggest we at least take a step back and look at it from an energy transition standpoint.
If wars have been fought over oil (and we want to transition our energy anyway), then it seems that the market forces behind some of the fighting would be dissipated by transitioning to a future type of energy that for whatever reason is preferable (in this case, because it's cleaner for our air, water, land, etc.). Thus, I see a dual purpose behind transitioning to clean energy: to allow the people in the world to transition from economic pressures that some have used in the past for fighting (over fixed mining real estate) to economies based upon self-performance and initiative (building industries related to solar panel creation and integration). While it would not entirely transition because there are still material needs which include mining concerns, it is a less mining oriented business than fossil fuels, and thus would interrupt the utility of fighting over oil real estate. (The other of the dual purposes is that it's our next form of clean energy technologically and economically, which is why the parties are able to be interested in it in the first place, for diversification.)
That in itself should lend credence to the concept that people would naturally become more cooperative in such economies, thus leading to less fighting problems, such as wars, terrorists, battles, anti-humanity actions, etc.
None of this post takes away from my assertion that those currently working for peace are doing so far more than propaganda would want us to know. (To that point, I remark that I knew Middle East politics were too propagandized for me to learn anything about it so I ignored it until I could get honest information about it, so that meant I ignored it for my entire life, until I found an independent analyst in the last few years, in which case I immediately started studying it. That's why I realize it is hard for most people to understand what is going on over there: they have either been misinformed to the point of being totally wrong for the entire time they paid attention to it, or, like me until early 2017, ignored it since they knew the information was bad and still haven't come up with any reliable source of information they can trust. Can you believe that two years ago, I didn't even know the names of the major languages in that area, and I thought Syria was in Africa? Now, I can almost draw a map of half the countries in the Middle East, and I don't even know where Honduras is, and I thought Costa Rica was an island in the Carribean until a month ago!)
