There never has to be
Another fight, argument,
Or war ever again.
Love conquers all.

Every single one of us, from the moment we’re born to the second we die, is always doing, saying, and thinking what we think is the right thing to do. That’s not to say that other people think so or even that it is legal. If you think it’s the right thing to do to clap your hands and the wrong thing is to snap your fingers, you’re of course going to clap your hands. If your mom tells you not to take a cookie from the cookie jar, you know you’re not supposed to do it. From your point of view it’s worth the risk of getting caught and so you take the cookie because it’s the right thing to do from your point of view. If you’re 30 years old you may decide to rob a bank. You know that doing so is illegal, but you go ahead because (if you get away with it) your life will be easier. Every one of us is always doing, saying, and thinking what we think is right every moment of our lives. So how can you be angry with anybody? You just need to learn from one another. You work through the disagreements without arguing or fighting. You just enlighten each other of the other’s perspective. It works for 2 people just the same as for 3. There just needs to be a little more discussion and ideas thrown around. Similarly, it works for 5 people, 10 people, 100, 1000, and then you extrapolate out to country vs. country. So, by using this theory, there never has to be a war ever again. There will be disagreements because we’re all different colors, ages, religions, have different jobs, etc. However, there never has to be another fight, argument, or war.
