All this fighting... How long must it go on?
You say that as though there really might be a way to stop it. It just breeds even more hate and that's the way it will always be.
That's not true!
I don't know how to stop this but without a doubt we will have peace one day. As long as there are those who believe peace is possible, there still is hope.
