My point was that without human nature being changed, "true peace" to get world peace will not happen. We humans are too self focused in the end to attain true peace, much less world peace that has....
No squabbles over any kind of resources.
No greed, hoarding, envy, crime.
A satisfaction with one's life.
Sounds impossible doesn't it? We humans are never satisfied with our lives, searching for something that eludes us physically, but we don't find it in part because we are too focused on what our own gain could be.
This could be attained by greater levels of communication, but without a rewrite of our basic nature; even more communication will not solve the underlying issues that humanity has.
----------------------
Let's look at an alternative Versailles/Arms treaty.
A long time ago, someone had an alternative arms treaty that focused primarily on armies rather than navies. Running with that, and limiting armies to sizes only enough to defend their countries' present borders while restricting navies from building capital sized ships [BBs, CVs, BCs, LCAs, etc] while allowing latitude to build enough smaller ships for commerce lane patrols and such. Something towards peace could be achieved with this, but [as stated below] everyone wants a degree of self sufficiency.
Part of the problem with self sufficiency was the scientific advancements sprouting up all over from late 1800s on, and suddenly you had to engage in international diplomacy for things that one never thought they would ever need before. Materials for electricity conduction and production, items of greater mobility than the horse and buggy that could be used for transportation and industry. This greatly expanded the definition of self sufficiency to the point of misinterpretation at a national level, because again; every nation looked to the benefits for themselves. Those who had to bargain for those materials to a degree or more became envious of those controlling the resources, thusly resulting in what we know as the world wars.
Now, if any of you started a reply already that perhaps includes some form of the word "but", then you have just validated my earlier point that we humans are too selfish for world peace [or see above].
We like peace, but as the naval treaties and subsequent world events spiraling from that era have shown; humans like security even more. We want to be secure and to feel safe, the Naval treaties canceled out that feeling of safety.
This is a good thought exercise to do, but the main point is that on our own terms, we humans will not have true peace without either complete self-extinction or otherworldly/supernatural help.
