Find peace within your consciousness. The rest will follow.

When you try to make peace by trying to prevent war and suffering, you invariably find yourself engaging in it within yourself and you are un-willingly feeding the flame of creation with your suffering as well.

(Added later, ruining the original answer, but it's more fun) So essentially, you teach those who are at war to be at peace within themselves.

And after achieving such peace throughout the land if you notice someone instigating war, throw them in jail in throw away the keys immediately.

So for example, if you want to get rid of terrorism on this planet, don't waste you time with the end result, instead follow the money/profit trail and get rid of the instigators and their institutions.

It's easy to find the real culprits. They are the first to tell you who was at fault.

I would suggest to the fighters that if they want to stop fighting they need to Focus on ThemSelves and stop blaming the other side. It's never about the other side, it's always about You. Also I think that for lasting peace on the Earth it would be helpful if we erased all these country boundries from the map and think of ourselves like One big nation cooperating together, because what happens in one place affects all the other places. Love Love Love yourself and your neighbor. Check out the works of Ghandi, Mandela, and MLKjr. Peace

I think I would listen without interrupting (kinda hard to do). So I'd make it people have to listen more than they speak perhaps.
