No Stupid Questions

Humans need to evolve to a state where love, compassion and being helpful to others is ingrained. At the moment we're just clever beasts.

Sadly though, I don't think we have enough time.

Universal basic income, universal food and shelter and education.

Make the old men fight each other and soilder just refusing to follow orders that seem stupid

Create an Artificial General Intelligence with the sole purpose of satisfying people's values through friendship and ponies.

Abolish Money and increase global distribution of goods aka socialism.

Easy enough, we just build a jail so big that we can fit the entire world inside of it, boom no more crime.

It's (theoretically) impossible -- you can't break someone's (ignorant and established) will/ideas/plans with words alone or treats. Most world leaders are megalomaniacs by heart, i.e they won't stop until they are done with what they want.

Put everyone in a time-out until they can play nicely with the other children (because let's face it, a lot of them are acting like children)

Humans are gonna human unfortunately. Biologically I’m not convinced we are capable of eliminating war because humans are competitive by nature. To the point that there will always be one group or another trying to force its ideals onto another.

I’ve often thought about “what if we could snap our fingers and every weapon beyond that of a spear (technologically) was vanished, and any/every attempt to fashion something deadlier would fail/poof out of existence as well.”

That might stave off large scale war but there would still be tribal warring on a smaller scale I fear. Plus a ton of other issues that would arise from suddenly having no guns/missiles/projectiles/etc.

this is a bit grim but global-wide information control that shreds any information which will help the growth of the idea of overly patriotic but less enough to not kill the domestic culture (but i think, not necessarily always telling the truth). that will also promote the sense of global village and transnationalism. and relocate the idea of war to other rivalries like on sports or something, idk.

basically limit the free will without showing it. I can't think if it's gonna happen or this even possible.

No hands for anyone. Possibly no feet too. Only the cooperative will survive.

Well effectively, it would entail an all-encompassing global spying machine that gathers all data possible, and imprisons anyone who deviates from the expected baseline. (Wouldn’t end well for me either.) You have to remove most individuality to remove reasons for fighting. And even if you imprison 999 false leads to capture just one instigator, that’s the only way to ‘guarantee’ a fairly high level of security.

So what I’d say we need is 1984 or Мы levels of oversight to have any chance of curtailing conflict for good.

Simple. We make war illegal.

I think the solution is to have enough renewable energy for all of humanity.

Implantation of the post-scarcity society and the end of capitalism ez gg

Communication? Make Marshall Rosenberg a school subject?

At the core, I feel it practically always comes down to perceived advantage in a multipolar trap, spread through power hierarchies and bad faith communication.

If you see war as a struggle to get access to scarce resources and if you notice that currently humankind is depleting most of the available resources then you might come to the conclusion that if in the future we will not need to go to war something terrible must have happened. Are you sure about the future you want?

There is no solution to that. It is a cold, hard reality of living on a planet with limited resources. We all might hate war (and for good reason, obviously), but it isn't like animals don't fight for territory either. Just happens that humans found a way to make it a few orders of magnitude more extreme.

Make tea

Put the ones in charge to the front line.

Post scarcity, de-population, or colonization of new worlds.

It would take way more but the first step it would be to remove religions. And not only because most are not peaceful in principle but also because some religions see others as a target. Even small difference in beliefs could spark a vicious and long standing conflic, like Catholics Vs protestants.
