I agree with Sroor. Every person understands peace individually. I want to see a public peace process and I decided I did not want to wait for the politicians to make peace. This is why I started mepeace. And thank you for participating in this peace process.
Encourage more and more ordinary people from both sides to meet and talk with each other more and more often, in an emotionally and physically safe environment. I would initially simply focus on trying to demistify "the other". And avoid concepts like PEACE and especially JUSTICE because perceptions about these are often so subjective.
That may be a good theory! But doing that is not easy.
mepeace.org can be one such opportunity. I hope so.
